Planka on Proxmox, Daily Error: connect ECONNREFUSED (a solution)

[UhlhornHH]

Planka went down every day at around 08:30 in the morning, the website was constantly loading. Docker ps showed the status that the container had just been restarted a few seconds ago. The container was constantly restarting.

Uptime Kuma shows the error message: connect ECONNREFUSED 10.0.20.xxx:xxxx.

If you stop the container once and then restart it, Planka gets available again until the next day at the same time.

So, I found out that backing up the Proxmox container with the "Stop" mode triggers the problem. If I change the mode to "Suspend", it works.

Maybe it will help someone who has similar problems.
