Why is my server accessible, but websites and control panel are not?
Just created a new Plesk droplet, migrated two WordPress installations, hadn’t touched anything and access to everything (Plesk, websites) became inaccessible overnight (ERRCONNECTIONTIMED_OUT).
I found that UFW had somehow blocked everything incoming/outgoing, so I disabled it, and everything was accessible, but the next day the same thing began occurring. I checked and UFW is still disabled, I’ve tried restarting all services, and rebooting the server, but nothing.
Any ideas what this could be or where to start looking?
