The outpost upstream was being passed directly to Caddy's dial field with the
full URL (http://host:port), but Caddy expects just host:port. This was causing
DNS lookup errors with a leading slash (/authentik.bologna.local.fuo.fi).
Now properly parses the URL to extract just the hostname and port.
The outpost route now preserves the original request host (e.g., email.fuo.fi)
instead of changing it to the upstream host. This allows Authentik to properly
construct redirect URLs after processing authentication callbacks.
- Replace AbortSignal.timeout() with AbortController for better compatibility
- Add detailed error logging to diagnose connection failures
- Improve health status logging (only warn once when becoming unhealthy)
- Add logging when Caddy recovers from unhealthy state
- Add current state to initialization log for debugging
This fixes the monitoring service continuously reporting failures and improves
restart detection after OOM crashes or container restarts.
