So I booted up my Minecraft server for TLauncher, and then after I activated it my friend says it kept on kicking him from it. I asked him what the error message was, but he didn't respond. I tried it myself, and I entered it with no problems. But then after a few minutes, it said ''Connection lost, timed out'' after I tried to join again it only says ''Connecting to server'' and doesn't let me join. I tried multiple times by restarting the server, but it didn't work. And when my friend joins and then leaves, on the player count where it says how many players joined the server, it says that my friend is still there, even though he left.
I don't know what to do, here are the logs https://mclo.gs/rag7Hrp If anyone helps thank you a ton! Because we put a lot of effort into the server and builds.
