# Troubleshooting

# Gateway troubleshooting

This page is the deep runbook.
Start at [/help/troubleshooting](/help/troubleshooting) if you want the fast triage flow first.

## Command ladder

Run these first, in this order:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz status
fluffbuzz gateway status
fluffbuzz logs --follow
fluffbuzz doctor
fluffbuzz channels status --probe
```

Expected healthy signals:

* `fluffbuzz gateway status` shows `Runtime: running`, `Connectivity probe: ok`, and a `Capability: ...` line.
* `fluffbuzz doctor` reports no blocking config/service issues.
* `fluffbuzz channels status --probe` shows live per-account transport status and,
  where supported, probe/audit results such as `works` or `audit ok`.

## Anthropic 429 extra usage required for long context

Use this when logs/errors include:
`HTTP 429: rate_limit_error: Extra usage is required for long context requests`.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz logs --follow
fluffbuzz models status
fluffbuzz config get agents.defaults.models
```

Look for:

* Selected Anthropic Opus/Sonnet model has `params.context1m: true`.
* Current Anthropic credential is not eligible for long-context usage.
* Requests fail only on long sessions/model runs that need the 1M beta path.

Fix options:

1. Disable `context1m` for that model to fall back to the normal context window.
2. Use an Anthropic credential that is eligible for long-context requests, or switch to an Anthropic API key.
3. Configure fallback models so runs continue when Anthropic long-context requests are rejected.

## Local OpenAI-compatible backend passes direct probes but agent runs fail

Use this when:

* `curl ... /v1/models` works
* tiny direct `/v1/chat/completions` calls work
* FluffBuzz model runs fail only on normal agent turns

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl http://127.0.0.1:1234/v1/models
curl http://127.0.0.1:1234/v1/chat/completions \
  -H 'content-type: application/json' \
  -d '{"model":"<id>","messages":[{"role":"user","content":"hi"}],"stream":false}'
fluffbuzz infer model run --model <provider/model> --prompt "hi" --json
fluffbuzz logs --follow
```

Look for:

* direct tiny calls succeed, but FluffBuzz runs fail only on larger prompts
* backend errors about `messages[].content` expecting a string
* backend crashes that appear only with larger prompt-token counts or full agent
  runtime prompts

Common signatures:

* `messages[...].content: invalid type: sequence, expected a string` → backend
  rejects structured Chat Completions content parts. Fix: set
  `models.providers.<provider>.models[].compat.requiresStringContent: true`.
* direct tiny requests succeed, but FluffBuzz agent runs fail with backend/model
  crashes (for example Gemma on some `inferrs` builds) → FluffBuzz transport is
  likely already correct; the backend is failing on the larger agent-runtime
  prompt shape.
* failures shrink after disabling tools but do not disappear → tool schemas were
  part of the pressure, but the remaining issue is still upstream model/server
  capacity or a backend bug.

Fix options:

1. Set `compat.requiresStringContent: true` for string-only Chat Completions backends.
2. Set `compat.supportsTools: false` for models/backends that cannot handle
   FluffBuzz's tool schema surface reliably.
3. Lower prompt pressure where possible: smaller workspace bootstrap, shorter
   session history, lighter local model, or a backend with stronger long-context
   support.
4. If tiny direct requests keep passing while FluffBuzz agent turns still crash
   inside the backend, treat it as an upstream server/model limitation and file
   a repro there with the accepted payload shape.

## No replies

If channels are up but nothing answers, check routing and policy before reconnecting anything.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz status
fluffbuzz channels status --probe
fluffbuzz pairing list --channel <channel> [--account <id>]
fluffbuzz config get channels
fluffbuzz logs --follow
```

Look for:

* Pairing pending for DM senders.
* Group mention gating (`requireMention`, `mentionPatterns`).
* Channel/group allowlist mismatches.

Common signatures:

* `drop guild message (mention required` → group message ignored until mention.
* `pairing request` → sender needs approval.
* `blocked` / `allowlist` → sender/channel was filtered by policy.

## Dashboard control ui connectivity

When dashboard/control UI will not connect, validate URL, auth mode, and secure context assumptions.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz gateway status
fluffbuzz status
fluffbuzz logs --follow
fluffbuzz doctor
fluffbuzz gateway status --json
```

Look for:

* Correct probe URL and dashboard URL.
* Auth mode/token mismatch between client and gateway.
* HTTP usage where device identity is required.

Common signatures:

* `device identity required` → non-secure context or missing device auth.
* `origin not allowed` → browser `Origin` is not in `gateway.controlUi.allowedOrigins`
  (or you are connecting from a non-loopback browser origin without an explicit
  allowlist).
* `device nonce required` / `device nonce mismatch` → client is not completing the
  challenge-based device auth flow (`connect.challenge` + `device.nonce`).
* `device signature invalid` / `device signature expired` → client signed the wrong
  payload (or stale timestamp) for the current handshake.
* `AUTH_TOKEN_MISMATCH` with `canRetryWithDeviceToken=true` → client can do one trusted retry with cached device token.
* That cached-token retry reuses the cached scope set stored with the paired
  device token. Explicit `deviceToken` / explicit `scopes` callers keep their
  requested scope set instead.
* Outside that retry path, connect auth precedence is explicit shared
  token/password first, then explicit `deviceToken`, then stored device token,
  then bootstrap token.
* On the async Tailscale Serve Control UI path, failed attempts for the same
  `{scope, ip}` are serialized before the limiter records the failure. Two bad
  concurrent retries from the same client can therefore surface `retry later`
  on the second attempt instead of two plain mismatches.
* `too many failed authentication attempts (retry later)` from a browser-origin
  loopback client → repeated failures from that same normalized `Origin` are
  locked out temporarily; another localhost origin uses a separate bucket.
* repeated `unauthorized` after that retry → shared token/device token drift; refresh token config and re-approve/rotate device token if needed.
* `gateway connect failed:` → wrong host/port/url target.

### Auth detail codes quick map

Use `error.details.code` from the failed `connect` response to pick the next action:

| Detail code                  | Meaning                                                                                                                                                                                      | Recommended action                                                                                                                                                                                                                                                                       |
| ---------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `AUTH_TOKEN_MISSING`         | Client did not send a required shared token.                                                                                                                                                 | Paste/set token in the client and retry. For dashboard paths: `fluffbuzz config get gateway.auth.token` then paste into Control UI settings.                                                                                                                                             |
| `AUTH_TOKEN_MISMATCH`        | Shared token did not match gateway auth token.                                                                                                                                               | If `canRetryWithDeviceToken=true`, allow one trusted retry. Cached-token retries reuse stored approved scopes; explicit `deviceToken` / `scopes` callers keep requested scopes. If still failing, run the [token drift recovery checklist](/cli/devices#token-drift-recovery-checklist). |
| `AUTH_DEVICE_TOKEN_MISMATCH` | Cached per-device token is stale or revoked.                                                                                                                                                 | Rotate/re-approve device token using [devices CLI](/cli/devices), then reconnect.                                                                                                                                                                                                        |
| `PAIRING_REQUIRED`           | Device identity needs approval. Check `error.details.reason` for `not-paired`, `scope-upgrade`, `role-upgrade`, or `metadata-upgrade`, and use `requestId` / `remediationHint` when present. | Approve pending request: `fluffbuzz devices list` then `fluffbuzz devices approve <requestId>`. Scope/role upgrades use the same flow after you review the requested access.                                                                                                             |

Device auth v2 migration check:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz --version
fluffbuzz doctor
fluffbuzz gateway status
```

If logs show nonce/signature errors, update the connecting client and verify it:

1. waits for `connect.challenge`
2. signs the challenge-bound payload
3. sends `connect.params.device.nonce` with the same challenge nonce

If `fluffbuzz devices rotate` / `revoke` / `remove` is denied unexpectedly:

* paired-device token sessions can manage only **their own** device unless the
  caller also has `operator.admin`
* `fluffbuzz devices rotate --scope ...` can only request operator scopes that
  the caller session already holds

## Gateway service not running

Use this when service is installed but process does not stay up.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz gateway status
fluffbuzz status
fluffbuzz logs --follow
fluffbuzz doctor
fluffbuzz gateway status --deep   # also scan system-level services
```

Look for:

* `Runtime: stopped` with exit hints.
* Service config mismatch (`Config (cli)` vs `Config (service)`).
* Port/listener conflicts.
* Extra launchd/systemd/schtasks installs when `--deep` is used.
* `Other gateway-like services detected (best effort)` cleanup hints.

Common signatures:

* `Gateway start blocked: set gateway.mode=local` or `existing config is missing gateway.mode` → local gateway mode is not enabled, or the config file was clobbered and lost `gateway.mode`. Fix: set `gateway.mode="local"` in your config, or re-run `fluffbuzz onboard --mode local` / `fluffbuzz setup` to restamp the expected local-mode config. If you are running FluffBuzz via Podman, the default config path is `~/.fluffbuzz/fluffbuzz.json`.
* `refusing to bind gateway ... without auth` → non-loopback bind without a valid gateway auth path (token/password, or trusted-proxy where configured).
* `another gateway instance is already listening` / `EADDRINUSE` → port conflict.
* `Other gateway-like services detected (best effort)` → stale or parallel launchd/systemd/schtasks units exist. Most setups should keep one gateway per machine; if you do need more than one, isolate ports + config/state/workspace. See [/gateway#multiple-gateways-same-host](/gateway#multiple-gateways-same-host).

## Gateway restored last-known-good config

Use this when the Gateway starts, but logs say it restored `fluffbuzz.json`.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz logs --follow
fluffbuzz config file
fluffbuzz config validate
fluffbuzz doctor
```

Look for:

* `Config auto-restored from last-known-good`
* `gateway: invalid config was restored from last-known-good backup`
* `config reload restored last-known-good config after invalid-config`
* A timestamped `fluffbuzz.json.clobbered.*` file beside the active config
* A main-agent system event that starts with `Config recovery warning`

What happened:

* The rejected config did not validate during startup or hot reload.
* FluffBuzz preserved the rejected payload as `.clobbered.*`.
* The active config was restored from the last validated last-known-good copy.
* The next main-agent turn is warned not to blindly rewrite the rejected config.

Inspect and repair:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
CONFIG="$(fluffbuzz config file)"
ls -lt "$CONFIG".clobbered.* "$CONFIG".rejected.* 2>/dev/null | head
diff -u "$CONFIG" "$(ls -t "$CONFIG".clobbered.* 2>/dev/null | head -n 1)"
fluffbuzz config validate
fluffbuzz doctor
```

Common signatures:

* `.clobbered.*` exists → an external direct edit or startup read was restored.
* `.rejected.*` exists → an FluffBuzz-owned config write failed schema or clobber checks before commit.
* `Config write rejected:` → the write tried to drop required shape, shrink the file sharply, or persist invalid config.
* `missing-meta-vs-last-good`, `gateway-mode-missing-vs-last-good`, or `size-drop-vs-last-good:*` → startup treated the current file as clobbered because it lost fields or size compared with the last-known-good backup.
* `Config last-known-good promotion skipped` → the candidate contained redacted secret placeholders such as `***`.

Fix options:

1. Keep the restored active config if it is correct.
2. Copy only the intended keys from `.clobbered.*` or `.rejected.*`, then apply them with `fluffbuzz config set` or `config.patch`.
3. Run `fluffbuzz config validate` before restarting.
4. If you edit by hand, keep the full JSON5 config, not just the partial object you wanted to change.

## Gateway probe warnings

Use this when `fluffbuzz gateway probe` reaches something, but still prints a warning block.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz gateway probe
fluffbuzz gateway probe --json
fluffbuzz gateway probe --ssh user@gateway-host
```

Look for:

* `warnings[].code` and `primaryTargetId` in JSON output.
* Whether the warning is about SSH fallback, multiple gateways, missing scopes, or unresolved auth refs.

Common signatures:

* `SSH tunnel failed to start; falling back to direct probes.` → SSH setup failed, but the command still tried direct configured/loopback targets.
* `multiple reachable gateways detected` → more than one target answered. Usually this means an intentional multi-gateway setup or stale/duplicate listeners.
* `Read-probe diagnostics are limited by gateway scopes (missing operator.read)` → connect worked, but detail RPC is scope-limited; pair device identity or use credentials with `operator.read`.
* `Capability: pairing-pending` or `gateway closed (1008): pairing required` → the gateway answered, but this client still needs pairing/approval before normal operator access.
* unresolved `gateway.auth.*` / `gateway.remote.*` SecretRef warning text → auth material was unavailable in this command path for the failed target.

## Channel connected messages not flowing

If channel state is connected but message flow is dead, focus on policy, permissions, and channel specific delivery rules.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz channels status --probe
fluffbuzz pairing list --channel <channel> [--account <id>]
fluffbuzz status --deep
fluffbuzz logs --follow
fluffbuzz config get channels
```

Look for:

* DM policy (`pairing`, `allowlist`, `open`, `disabled`).
* Group allowlist and mention requirements.
* Missing channel API permissions/scopes.

Common signatures:

* `mention required` → message ignored by group mention policy.
* `pairing` / pending approval traces → sender is not approved.
* `missing_scope`, `not_in_channel`, `Forbidden`, `401/403` → channel auth/permissions issue.

* [/channels/telegram](/channels/telegram)
* [/channels/discord](/channels/discord)

## Cron and heartbeat delivery

If cron or heartbeat did not run or did not deliver, verify scheduler state first, then delivery target.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz cron status
fluffbuzz cron list
fluffbuzz cron runs --id <jobId> --limit 20
fluffbuzz system heartbeat last
fluffbuzz logs --follow
```

Look for:

* Cron enabled and next wake present.
* Job run history status (`ok`, `skipped`, `error`).
* Heartbeat skip reasons (`quiet-hours`, `requests-in-flight`, `alerts-disabled`, `empty-heartbeat-file`, `no-tasks-due`).

Common signatures:

* `cron: scheduler disabled; jobs will not run automatically` → cron disabled.
* `cron: timer tick failed` → scheduler tick failed; check file/log/runtime errors.
* `heartbeat skipped` with `reason=quiet-hours` → outside active hours window.
* `heartbeat skipped` with `reason=empty-heartbeat-file` → `HEARTBEAT.md` exists but only contains blank lines / markdown headers, so FluffBuzz skips the model call.
* `heartbeat skipped` with `reason=no-tasks-due` → `HEARTBEAT.md` contains a `tasks:` block, but none of the tasks are due on this tick.
* `heartbeat: unknown accountId` → invalid account id for heartbeat delivery target.
* `heartbeat skipped` with `reason=dm-blocked` → heartbeat target resolved to a DM-style destination while `agents.defaults.heartbeat.directPolicy` (or per-agent override) is set to `block`.

## Node paired tool fails

If a node is paired but tools fail, isolate foreground, permission, and approval state.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz nodes status
fluffbuzz nodes describe --node <idOrNameOrIp>
fluffbuzz approvals get --node <idOrNameOrIp>
fluffbuzz logs --follow
fluffbuzz status
```

Look for:

* Node online with expected capabilities.
* OS permission grants for camera/mic/location/screen.
* Exec approvals and allowlist state.

Common signatures:

* `NODE_BACKGROUND_UNAVAILABLE` → node app must be in foreground.
* `*_PERMISSION_REQUIRED` / `LOCATION_PERMISSION_REQUIRED` → missing OS permission.
* `SYSTEM_RUN_DENIED: approval required` → exec approval pending.
* `SYSTEM_RUN_DENIED: allowlist miss` → command blocked by allowlist.

* [/nodes/troubleshooting](/nodes/troubleshooting)
* [/nodes/index](/nodes/index)
* [/tools/exec-approvals](/tools/exec-approvals)

## Browser tool fails

Use this when browser tool actions fail even though the gateway itself is healthy.

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz browser status
fluffbuzz browser start --browser-profile fluffbuzz
fluffbuzz browser profiles
fluffbuzz logs --follow
fluffbuzz doctor
```

Look for:

* Whether `plugins.allow` is set and includes `browser`.
* Valid browser executable path.
* CDP profile reachability.
* Local Chrome availability for `existing-session` / `user` profiles.

Common signatures:

* `unknown command "browser"` or `unknown command 'browser'` → the bundled browser plugin is excluded by `plugins.allow`.
* browser tool missing / unavailable while `browser.enabled=true` → `plugins.allow` excludes `browser`, so the plugin never loaded.
* `Failed to start Chrome CDP on port` → browser process failed to launch.
* `browser.executablePath not found` → configured path is invalid.
* `browser.cdpUrl must be http(s) or ws(s)` → the configured CDP URL uses an unsupported scheme such as `file:` or `ftp:`.
* `browser.cdpUrl has invalid port` → the configured CDP URL has a bad or out-of-range port.
* `Could not find DevToolsActivePort for chrome` → Chrome MCP existing-session could not attach to the selected browser data dir yet. Open the browser inspect page, enable remote debugging, keep the browser open, approve the first attach prompt, then retry. If signed-in state is not required, prefer the managed `fluffbuzz` profile.
* `No Chrome tabs found for profile="user"` → the Chrome MCP attach profile has no open local Chrome tabs.
* `Remote CDP for profile "<name>" is not reachable` → the configured remote CDP endpoint is not reachable from the gateway host.
* `Browser attachOnly is enabled ... not reachable` or `Browser attachOnly is enabled and CDP websocket ... is not reachable` → attach-only profile has no reachable target, or the HTTP endpoint answered but the CDP WebSocket still could not be opened.
* `Playwright is not available in this gateway build; '<feature>' is unsupported.` → the current gateway install lacks the bundled browser plugin's `playwright-core` runtime dependency; run `fluffbuzz doctor --fix`, then restart the gateway. ARIA snapshots and basic page screenshots can still work, but navigation, AI snapshots, CSS-selector element screenshots, and PDF export stay unavailable.
* `fullPage is not supported for element screenshots` → screenshot request mixed `--full-page` with `--ref` or `--element`.
* `element screenshots are not supported for existing-session profiles; use ref from snapshot.` → Chrome MCP / `existing-session` screenshot calls must use page capture or a snapshot `--ref`, not CSS `--element`.
* `existing-session file uploads do not support element selectors; use ref/inputRef.` → Chrome MCP upload hooks need snapshot refs, not CSS selectors.
* `existing-session file uploads currently support one file at a time.` → send one upload per call on Chrome MCP profiles.
* `existing-session dialog handling does not support timeoutMs.` → dialog hooks on Chrome MCP profiles do not support timeout overrides.
* `response body is not supported for existing-session profiles yet.` → `responsebody` still requires a managed browser or raw CDP profile.
* stale viewport / dark-mode / locale / offline overrides on attach-only or remote CDP profiles → run `fluffbuzz browser stop --browser-profile <name>` to close the active control session and release Playwright/CDP emulation state without restarting the whole gateway.

## If you upgraded and something suddenly broke

Most post-upgrade breakage is config drift or stricter defaults now being enforced.

### 1) Auth and URL override behavior changed

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz gateway status
fluffbuzz config get gateway.mode
fluffbuzz config get gateway.remote.url
fluffbuzz config get gateway.auth.mode
```

What to check:

* If `gateway.mode=remote`, CLI calls may be targeting remote while your local service is fine.
* Explicit `--url` calls do not fall back to stored credentials.

Common signatures:

* `gateway connect failed:` → wrong URL target.
* `unauthorized` → endpoint reachable but wrong auth.

### 2) Bind and auth guardrails are stricter

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz config get gateway.bind
fluffbuzz config get gateway.auth.mode
fluffbuzz config get gateway.auth.token
fluffbuzz gateway status
fluffbuzz logs --follow
```

What to check:

* Non-loopback binds (`lan`, `tailnet`, `custom`) need a valid gateway auth path: shared token/password auth, or a correctly configured non-loopback `trusted-proxy` deployment.
* Old keys like `gateway.token` do not replace `gateway.auth.token`.

Common signatures:

* `refusing to bind gateway ... without auth` → non-loopback bind without a valid gateway auth path.
* `Connectivity probe: failed` while runtime is running → gateway alive but inaccessible with current auth/url.

### 3) Pairing and device identity state changed

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz devices list
fluffbuzz pairing list --channel <channel> [--account <id>]
fluffbuzz logs --follow
fluffbuzz doctor
```

What to check:

* Pending device approvals for dashboard/nodes.
* Pending DM pairing approvals after policy or identity changes.

Common signatures:

* `device identity required` → device auth not satisfied.
* `pairing required` → sender/device must be approved.

If the service config and runtime still disagree after checks, reinstall service metadata from the same profile/state directory:

```bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fluffbuzz gateway install --force
fluffbuzz gateway restart
```
