SSH Connection Test Not Working

I am trying to test my connection to my new SSH using the instructions in Testing your SSH connection - GitHub Docs but every time I try the connection times out.

SSH Connection Issue

Am I doing something wrong? Is there another way to test the connection?

The command as such looks like it should work, though adding -v would give you some more debug information:

ssh -vT

A timeout is most commonly caused by network or firewall issues, which are hard to debug remotely. The screenshot looks like you’re using a VM, maybe its networking setup isn’t quite right, or the host doesn’t forward packets for it?
