Troubleshooting

Checks alternating between 200 and 403/401 - switch to a Browser monitor or raise the interval to 2+ minutes. Many WAFs rate-limit headless traffic.

Timeouts without an error body - inspect the redirect chain (on the detail page) and run a traceroute from the same region. The failure is usually upstream.

Heartbeat shows MISS right after creation - make sure your cron/task actually runs and that the token URL is correct. Use curl -v from the target machine to confirm egress.

Dashboard state looks stale after the tab was backgrounded - refresh once to force a full API sync. Real-time SSE reconnects automatically but catch-up relies on the initial load.

Trigger stopped firing - check the execution log on the trigger. The circuit breaker auto-disables after 10 consecutive failures; owner gets an in-app notification when that happens.
