I was trying to set up a new homelab server the other day, and I stumbled upon this frustrating issue.

At first, I thought it was a firewall problem, but after checking the rules, I realized that wasn't the case.

After some digging, I discovered that the issue was due to the SSH service not being enabled on the server.
I know, I know, it sounds like a rookie mistake!

But here's the thing: I had enabled the service, but I hadn't restarted it after making some configuration changes.

The command 'sudo systemctl restart sshd' saved the day.

It got me thinking, though - what other services might be in a similar state?

I started checking the status of other services, and sure enough, I found a few that needed a restart.

Moral of the story: always double-check the service status after making changes, and don't be afraid to restart when necessary.
