I'm unable to SSH into my Microsoft Azure VM. Attempting to SSH in via Terminal is met with either "Connection closed by 220.127.116.11 port 22" or "Connection reset by 18.104.22.168 port 22" and attempting to connect via PuTTY resulted in a fatal error reading "Remote side unexpectedly closed network connection". The basic troubleshooting steps have been ineffective. One of my team members modified the permissions of /var on the server right before the issues began, leading us to believe that may be the cause of the issue. Any assistance in resolving this issue would be much appreciated.
