I can't go in to the server

Hello! I’m new here and wanted to check out the server. I did as the tutorial told me to and everything went good, but when I’ve whritten in the ip and wanna log in it says “Failed to connect to the server, unknown host” and when i don’t click at the server it also says “can’t resolve hostname”. I just wonder if you know how to fix this and if it’s me or you that makes this, thank u for your time. (btw sorry for bad spelling).

You sure the IP you used was correct?

Oh, I must have missed something, it works now anyways. Thank u! :wink:
