are you attempting connection direct to....

...Your home IP address, or it's domain name? The first thing you hit at home IP would be your router, unless you have a DMZ to your server.

Let's say you forwarded port 4040. Your ip was, then you'd put into your browser.

Since you understand Linux

Have you tried booting the school PC to a USB live linux distro, and seeing if you could then access your home server? If you still can't, then you are back to what Kees suggested, the school is blocking it for some reason.

The question then would be "why is the school blocking your home server and not others"?

Most likely answer would be they subscribe to some positive based verification service and it blocks all that aren't approved already. In that case you'd need to know what the service is and get whitelisted on it.

your phone goes through a different network using your data plan, so the school has nothing to do with it.

If it works from any other location and not from your school, it definitely is something in their network or with their ISP.
And so they are the only one that can solve it.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
