[Bug]: Servers become unreachable

[Schroedi]

Error Message and Logs

I started to encounter strange problems on both of my servers in Coolify cloud:
Project deployments fail with (last deployment was 3 weeks ago and successful)

[CMD]: sudo docker rm -f no0scg44og4gkkok444ckgk0 >/dev/null 2>&1
[email protected]: Permission denied (publickey,password).

Now both servers are marked as offline. I can access them via the terminal on the server page but not the "Terminal" main menu (there nothing is listed).
When I validate the server, it is marked as online again but becomes unreachable after some time (minutes). The coolify web terminal connection works after I re-validated the server. I can also restart the proxy (docker ps marks shows it as restarted x seconds ago).

In /var/log/auth.log I can see the successfull auth for the server validation. When I try to deploy an app, the log shows:

Any help on how to proceed with debugging would be appreciated.
