    Hi Ahmad,

    No worries, let’s get that sorted and disabled for you!

    1. Log into the Azure Portal
    2. Go to your Ubuntu VM
    3. Under Operations you should see ‘RunShellScript’ option
    4. enter either ufw disable or ufw allow ssh and run the command
    5. verify you’re now able to get back in via SSH

    This should resolve your issue by either allowing SSH through ufw or disabling it so you can manually configure once back on the machine.

    If this was then please mark the answer as accepted so others can benefit in the community.
