[BUG] Incompatible Mods (only when connecting to dedicated servers)

[Fundryi]

Is there an existing issue for this?

• [x] I have searched the existing issues

Current Behavior

When trying to connect to the server you get this error: https://i.imgur.com/oY72Kw5.png

[minecraft/ServerGamePacketListenerImpl]: Fundryi lost connection: Internal Exception: io.netty.handler.codec.EncoderException: java.lang.IllegalArgumentException: unable to fit 2098402 into 3

Expected Behavior

Being able to join the server :)

Steps To Reproduce

Client / Server Forge 47.1.3 Ender IO Client / Server 6.0.18 Simple Shops Client / Server 1.2.2

Environment

- OS: Windows
- Java version: CurseForge Default
- Minecraft version: 1.20.1
- Version: 6.0.18

Anything else?

Probably has something to-do with Item Stacking, since I had the exact same error with "Bigger Stacks" mod.

It looks like there are external factors at play here; i setup a server with EnderIO 6.0.18 and Simple Shops 1.2.2 and was able to connect to the server perfectly fine.

Hi, sorry I think I found the problem.

Could you try it with changing this value in the server.properties?

network-compression-threshold=-1

Since I changed it back to "network-compression-threshold=256" it works fine again. Its a very ood bug tbh, I doubt that should be happening.
