📝 Description

I've setup a basic monitor of a docker container. I've also setup a notification monitor to call a webhook when monitors go up/down.
The webhook is being called when the monitor goes down, but it's not being called when it goes back up.

Looking at my docker logs for UK, it seems that it detects the container as being down/exited. It then detects it as pending, but it never goes back to "up".

U.K. does now show that the autoheal container is Up, but there's nothing in the log, and no webhook triggered.

Any ideas?

👟 Reproduction steps

See above

👀 Expected behavior

Webhook should be called when container goes back Up.

😓 Actual Behavior

Webhook only being called when Container goes Down.

It does look like this might just be to do with this one container...
