Minecraft bedrock server not lan-discoverable #1343

Closed rcmoody closed 6 months ago

rcmoody commented 6 months ago

When running minecraft's official bedrock server for linux on raspberry pi (I'm using specifically the pi 4 model b) through box64, the server is not discoverable by clients under the friends tab.

It does appear however if I run natively on x64 hardware or if I use an alternative bedrock server such as nukkit, leading me to conclude this is an issue with box64.

I am able to connect to the server directly, it just doesn't appear under LAN worlds. Is it possible that box64 is not handling multicast packets properly?

Box64 should support it, but there might be some missing wrapped function or some struture needed some alignment between arm64 and x86_64 world.

Do you have more details on how bedrock server is doing it's network request?

rcmoody commented 6 months ago

It looks like minecraft bedrock uses the RakNet protocol. It is actually the client that broadcasts a message and the server that responds to it. However in this case the server simply isn't responding but the pi is indeed receiving the broadcast packets.

I ended up discovering that the reason my server was not discoverable under the friends tab was because I had already setup a direction connection under the servers tab which apparently precludes the former.
