Hi, a friend of mine plays on switch minecraft and i on the minecraft laptop, he doesn't come into my world and I don't like his
You probably don't have the same version, so it will be.
PS: do you play java or bedrock?
We both play on bedrock
Well because you probably do localhost and that only works if you are both in the same network.
How can you change that?
Not at all you would have to rent a server or request a time slot from a provider.
So 2 weeks ago he could still be on my world and then no more
Ok now I need a little more information - was he with you or were you with him?
Do you open the lan?
