I recently bought and played Minecraft Windows10 pc version, and the realms server goes in, but not the personal-created server (friends).

" Unable to connect to the world. You can no longer participate in the world. Unable to connect to world."
That's what it says. I'll attach the file.

Also, when someone else (friends) creates a server, the friend's server pops up, but when I create the server, the friend doesn't see my server. Even though he's an xbox follower.

I'd appreciate it if you could tell me the solution.
