Description

I've configured Uptime Kuma to monitor Docker containers by connecting the Docker socket.
I correctly receive notifications when a container goes down.
However, when the container comes back up, I don't receive any notification.

Is this a known issue, or is there a configuration I'm missing to enable "up" notifications for Docker containers? Any help would be appreciated!

ThankYou!

👟 Reproduction steps

👀 Expected behavior

I expected that when the monitored Docker container came back up, Uptime Kuma would send an "Up" notification, just as it successfully sends a "Down" notification when the container stops.

😓 Actual Behavior

Uptime Kuma successfully sent a "Down" notification when the container stopped, but it did not send an "Up" notification when the container restarted.
