SymptomLikely cause / fix
UntrustedHost in logsSet AUTH_TRUST_HOST=true in .env. Should be the default in newer compose templates.
Container restarts in a loopdocker compose logs app usually shows the cause — typically a missing required env or a DB connection error.
/setup returns 401Auth was saved before LLM + licence. docker compose down -v to wipe and start the wizard fresh.
Wizard shows "Unauthorized" on SavePre-2026-04-26 builds had a race condition where Next.js spawned before the engine bootstrap finished mirroring API_KEY into env. Pull :latest — fixed.
Chat hangs on first sendBad LLM API key. Check logs for 401 or 429. Re-test the key from /admin.
LICENSE_LOCKED thrown7-day grace period ran out without a successful licence verify. Paste a fresh key in /admin — the engine recovers without restart.
Platform warning on Apple SiliconPull a fresh image — multi-arch (amd64 + arm64) build is current. Old images run on Rosetta which is slow but functional.
Connectors all show as downExpected on first boot. Open /setup step 5 (or /admin → Connectors) and paste the credentials you actually use.
Voice/TTS audio doesn't playiOS Safari requires a user-gesture audio unlock. Tap the mic or send button once before expecting playback. Web Audio is suspended until then.
Trial email never arrivesCheck spam first. Then your RESEND_API_KEY on the marketing-site Worker, and that getkerno.ai is verified on Resend (DNS records propagated).
Sign-in fails after changing Google OAuth in /adminNextAuth reads GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET / ALLOWED_EMAIL / AUTH_SECRET only at Next.js startup. Run docker compose restart app to pick them up. Connector tokens and LLM keys hot-reload — only these four need a restart.
