I'm hoping someone can help me solve this once and for all - My son and I love playing vanilla minecraft over our wifi LAN, but suddenly I can't see or connect to his worlds anymore.
I have MacOSX (firewall off), he has Win8.1 (firewall configured to allow javaw.exe)
We're playing the same Version of Minecraft (1.9)
We both have our own Minecraft accounts
He can see and connect to my LAN worlds, but I can't see OR connect to his. Previously I couldn't SEE his world but I could direct connect to the ip (192.168.1.4:xxxxx). Now I can't do either.
Multiplayer listener Error Message:
Unable to start LAN server detection: Can't assign requested address
Direct Connection Error:
Connecting to 192.168.1.4, 25565 [12:23:58] [Server Connector #1/ERROR]: Couldn't connect to server io.netty.channel.ConnectTimeoutException: connection timed out: /192.168.1.4:25565 at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe$1.run(AbstractNioChannel.java:213) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at io.netty.util.concurrent.PromiseTask$RunnableAdapter.call(PromiseTask.java:38) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at io.netty.util.concurrent.ScheduledFutureTask.run(ScheduledFutureTask.java:123) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:380) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:357) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:116) ~[netty-all-4.0.23.Final.jar:4.0.23.Final] at java.lang.Thread.run(Thread.java:745) ~[?:1.8.0_74]
Questions:
What does the 'Unable to start LAN server detection: Can't assign requested address' error mean? Why can't I see his LAN games as available in the multiplayer list?
If I try to direct connect to the published port number (ex. 192.168.1.4:49970), why is my MC timing out trying to connect to 192.168.1.4, 25565? I searched for port 25565 and saw a bunch of messages about binding and port forwarding (I have no idea what that means) Would I need to do that for a LAN game?
I'd very much appreciate any help - I'm not very technical so please let me know if there's any other connection details or server information you might need.
As far as I know, the LAN server detection works by the client registering to receive multicast IP packets, and the only thing that would prevent this would be a firewall.
On the other hand, I have limited knowledge of OS X, and also there have been issues with IPv6 in the past, which I also have limited knowledge of.
Virtual interfaces for things like virtualbox, vmware, possibly vpn software may also cause difficulties sometimes, but I thought they were more on the Open to LAN hosting side than on the guest side.
Why are you connecting to 25565 if your son's port is 49970? That won't work. 25565 is the default port for regular servers. Open to LAN games use a randomized port that generally won't be 25565....
Have you confirmed that your computer's IP address is on the 192.168.1.x network?
