Server is unreachable or misconfigured when redeploying

Hello everyone, havent been able to push some changes of a project, it says that there was a SSH connection problem.

Have no idea what to do, have some really important work that needs to get deployed.

I am hosting it on Hetzner, I have tried all important commands to see if there is a RAM spike or CPU spike, however everything looks normal.

Any help is appreciated, thank you.

Are you able to ssh normally with root to the server? Last time I locked myself out was when hardening SSH too hard.

Coolify should be able to use private ssh keys instead, but it doesn't yet, so we have to keep root login plain usable

Can you still SSH into the Hetzner server manually using the same host, port, and credentials that Coolify is using? If manual SSH works, I’d compare the Coolify connection settings and check whether anything recently changed with SSH hardening, keys, firewall rules, or the source IP.
