When i go into my friends realm i disconnect after a few secounds

What happens is: i log into my friends free to play realm with 2 other persons. When they log in they can stay as long as they want to but when i do i lose connection and get kicked out where it says " internal Excaption: io.netty.handler.codec.decoder.exception: badly compressed packet - size of 89 is below server threshold of 256" and i have no idea how to fix it and i dont understand it. It also says " internal Excaption: io.netty.handler.codec.corruptedFrameException: length wider then 21-bit" also says " internal Excaption: io.netty.handler.codec.decoder.exception: java.util.zip.dataformatexception: incorrect header check"
