Description

I did docker update in one of my servers (services, not Uptime Kuma server) and after reboot it stopped working after 5 minutes.

Another server (Uptime Kuma) monitors it and all those crashed docker services in Uptime Kuma were stuck in "Pending" state for 12 hours before I noticed.

All those services have similar settings:
HTTP GET or JSON keyword montitor

All those services show similar "Pending" graph

👟 Reproduction steps

1. Make services you monitor offline
2. Let Reverse proxy keep working (Caddy)
3. Reverse proxy shows Error 502 in browser

👀 Expected behavior

If service is "Pending" for 12 hours it should be marked as down.
I guess 60 minutes is maximum to stay pending.

😓 Actual Behavior

Uptime Kuma stays in pending state for unlimited time (at least 12hours in my case)

Actual service went down around 23:35 and around 11:15 I started restart servers & debug docker failure.

Another strange graph where there is maintenace period (6-9AM) but it did not made to Telegram notifications previous picture.
