[1.7.10]LAN crash, only forge

[FLUFFY2]

I wanned to test out my mod in eclipse with 2 player so i made another run configuration and edited the name to ForgeDevName2.

If i start a dedicaded server it works. I can join, debug, ect...

If i start a LAN world, the player who wants to join crases with the following error:

NOTE:

Im using forge 1.7.10-10.13.0.1159 with Java 1.7!

Its the same with a clear SRC folder so my mod is not the problem.

That can be a bug i don't realy know.

You need to specify a uuid, or login for it to grab yours for you.

You CAN NOT connect to remote servers without it.

Thank you!

How am i supposed to specify a uuid? Can it be done in run configurations?

 

[LexManos]

Yes, it's a command line argument, you just need to pass in a correctly formatted uuid and it'll use it.

I'm apprechiate your help, but thats a bit high for me.

I stay with the login version.
