I have a Ubuntu VM that I used to be able to access via SSH. I've just installed some updates and restarted the VM. Now I can no longer connect - SSH gives a "connection refused" error message.
I've verified that the endpoint for TCP/22 still exists, and even created an explict ACL for my external IP address, with no luck.
The server is actually alive and answering HTTP requests.
Does anyone have a solution for this?
