Unable to find server on List/Direct Connect

I’ve ordered a VDS via NFOServers & set it up correctly;
The server launches but I’m unable to connect to it at all.

I’ve tried;

  • Port Forwarding (Didn’t work) No matter what I do in their command panel nothing works, still shows as “Closed” on any port checking website.
  • Reinstall
  • IPTables Forwarding.
  • Waiting for multiple heartbeats to be sent, still nothing.
