Ok.

I can't tell what the problem is but i can only tell to you:

Wait untill an admin replies and contact the provider.
Or check if the panel (check if it manage ports too) blocks the port.

Im sorry for the problem.

The panel is SolusVM. It doesn't block ports.
Also the VM seems to have networking problems which can only be fixed by recreating the VPS as far as I know. (It doesn't have the venet0 interface as I said)

Your IP Blocked By Your Own VPS???
Or The providers that blocked Your Ip??
Have you Try Restarting Your VPS ???

I also Often in SSH can not be used, the solution for myself was Restart VPS and Changing the IP Modem , Or Should Not Allow. backup all data and Reinstall the VPS

Obviously not to your first 2 questions. And to your third question, of course. It's the basics of troubleshooting.
As I said, ifconfig is empty. Even reconfigure networking didn't fix it. (Restarting and reinstalling are basics too. I also did that too of course )
