sshd service down (Error 500: got no worker upid - start worker failed)

[mitt]

The sshd service went down last night, and won't start, the error is as follows:

Connection failed (Error 500: got no worker upid - start worker failed)

Is there a way to fix it without restarting the server?

what does "journalctl -n 100" show immediately after you are trying to start the ssh? (or journalctl -f)

Currently i'm not being able to access the proxmox, since it does not respond through ssh, and the authentication through the web panel does not work either (Linux PAM standard authentication).

but the services work, only the sshd not.

the issue is that the datacenter is about 4 hours from my house, and I wanted to know if there was any way to solve it without having to restart, because otherwise I would have to go to the datacenter

Can you clarify how you are trying to start the service if the ssh is down and you said you cant login through GUI? What services are up?
What access do you have? How about console access? IPMI?

When the ssh started to fail, i was logged into the proxmox web panel with the session active, but it wouldn't let me use my node's console, and in the system section it said that the sshd was failing with that error I mentioned up. However, it was night, and I went to sleep. Today when I woke up, the session had expired and when trying to access, I could no longer access through the web panel (I guess it's because of ssh).

It sounds like you lost all access to PVE host, in that case reboot might be the only option. If you can find a way to access console that would be another way in.
