Hello. I'm currently trying to start a server through Aternos on 1.16.5, but every time I try to run the server, even though I am on the correct version of Minecraft and running it through Forge, I get this error message:
Internal Exception: java.lang.IndexOutOfBoundsException: readerIndex(42) + length(1) exceeds writerIndex(42): PooledUnsafeDirectByteBuf(ridx: 42, widx: 42, cap: 42)
I do not know the cause of this message. Can someone help?
