I am using putty to connect to my Ubuntu 16.04 VPS.
I decided to change the default SSH port from 22 to 443.
I did this changing the line
Port 22
in /etc/ssh/sshd_config
to Port 443
Now when I am trying to connect to the server using port 443 I get the error saying "Server unexpectedly closed network connection"
When I try to connect to the server using port 22 I get the error saying "Network error: Connection refused"
The server is up and running I just cannot connect to it anymore, is there anyway to fix this?

is there anyway to fix this?
- Use the system console (out of band connection) if available.
- Use the VPS recovery boot to mount the VPS disk and then edit the sshd_config file to reset the port to 22 from 443.
Less optimally
- Boot a new VPS instance, configure as per the first instance using your configuration management tools and recover from backups.
