My server wont show up

[Tornato7]

So i have 2 computers. I Made a server using the server manager on one and i wanted to play on the other. but when i go to multiplayer, i dont see my server. can someone help? thanks.

 

P.S. I don't understand too much of the technical stuff, so try to keep it simple.

Make sure all your ports the server runs on are cleared for server traffic. That's the firewall for the PC the server is running on.. and the router has a seperate firewall that needs to be cleared for server traffic on that line as well (usually).
