My friend has a 1.12.2 server which keeps kicking me randomly. We have about five friends on the server and I'm the only one to get kicked. Everytime I get kicked it has these "Internal Exception" messages on the "Connection Lost" screen. These messages include:

Internal Exception: io.netty.handler.codec.CorruptedFrameException: length wider than 21-bit
Internal Exception: io.netty.handler.codec.DecoderException: java.util.zip.DataFormatException: incorrect header check
Internal Exception: io.netty.handler.codec.DecoderException: Badly compressed packet - size of 70 is below server threshold of 256
Internal Exception: io.netty.handler.codec.DecoderException: java.lang.RuntimeException: VarInt too big

I have reinstalled Minecraft and Java.
