cannot log in to the server after changing SSH port
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.

Check if any web server is running with an active https site.
Should that be the case, stop the web server and restart the ssh demon.
