Dear Microsoft Support team,
Yesterday I created an Ubuntu 18 LTS VM server through Azure which I successfully connected to through an SSH connection with Putty on my Windows 10 laptop and I only used "sudo apt-get update" to check if everything was working normally in the terminal, thereafter I disconnected from the VM by typing the usual "exit" command and my connection was closed. However, today (less than 24 hours later) I don't seem to be able to connect through Putty at all on the same VM, same port, same username, same ppk, and same IP address at all as I get a "Connection timed out" error whenever I try to connect. Could this be a problem with either the VM or my computer? However, I did not install anything on my computer since yesterday and it was on "Sleep Mode" from the time I finished my work after exiting the VM and until now when I powered it up again.
Sincerely,
Said Alisic
