[Bug]: SSH often disconnects

[stag-enterprises]

I made this issue a while ago, and while a fix was supposedly released, either my issue is not the same or the fix does not work for me. I am on the latest release (380).

The issue is that Coolify will often connect to the SSH of the host machine, and then immediately disconnect. Attached are my SSH access logs. You can see Coolify disconnects after ~35 seconds (not the host kicking it, Coolify is closing the connection), and then will reconnect after about ~25 seconds.

This causes many problems in the dashboard, since the server is unreachable. For example, localhost server will appear as unvalidated most of the time, I am unable to access reverse proxy logs, most resources won't deploy most of the time, etc... On the dashboard side, it sometimes also throws an SSH error 22 to host.docker.internal with connection refused.

Coolify Version

v4.0.0-beta.380

I hit the same after installing latest coolify on brand new Debian VM with zero changes to /etc/ssh/sshd_config

In my case, as soon as the coolify containers come up, I can no longer ssh into the VM.

❯ ssh -v [email protected]

debug1: connect to address 192.168.1.103 port 22: Connection refused
ssh: connect to host 192.168.1.103 port 22: Connection refused

If I look at sudo journalctl -u ssh the only activity I see is from the coolify container on the docker network (10.0.1.6) repeatedly connecting and disconnecting (?)

External attempts to ssh in don't seem to even hit it the VM at all, feels like coolify takes over the port or something, not sure.

Additional info:

• If I restart the VM and I can ssh into it in the first few seconds before the coolify containers come up.
• If I uninstall coolify, the problem goes away and I can ssh into the VM just fine.
