Strange message that won't let me on a Minecraft server?

Does anyone know what that is? I get on all other servers, but not on the (AntiAC). I'm using Badlion Client 1.16.4, not Badlion AntiCheat.

I think you are missing 33 mods. Have to look on the server side.

and what kind of texture pack or client is that? I think it's beautiful

Badlion client is that

OK

I translated this with translator:

Internal connection exception: io.netty.handler.codec.DecoderException: javaio.1OException: Package 0/33 (pu) was larger than expected, while reading package 33, 252 bytes more were found

What kind of package is it 33?

Can you join the server without a badlion?

No idea, I would like to know myself

Yes, that's right, I actually can! Now I can definitely go back to the server. Thanks for that

Edit: it doesn't work. Not any longer longer. It shows exactly the same…

OK thanks

Look times in the MC folder with mods or server
