I've been using PuTTY on a Windows machine to access the server I have running in my garage for a few months now. No issues at all. I started using DirectAdmin on that server the other day for some management tasks and suddenly my SSH no longer works. I've tried uninstalling SSH from the server and reinstalling it, disabled the firewall to check that it wasn't a UFW problem, attempted to forward the port and connect from outside of my local network, and flushed DNS on the client side. I am totally lost and I've got no idea what to try next. I use this server commercially, so convenient access is super important. I always get the "Network error: Connection timed out" error on PuTTY. Any suggestions?
Edit: Ubuntu Server 22.04
