I have decided to play on Aternos with my friends on forge, using the Biomes O' Plenty mod. But when I try to join the server, it says:

Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/26 (pn) was larger than I expected, found 169 bytes extra whilst reading packet 26"

- I am playing on 1.16.3 forge
- I have set the aternos server on forge as well
- I joined on the valid version

- I have the Biomes O' Plenty mod only

- I have set the world type BIOMESOP

- I am using TLauncher
