Getting Unknown serializer type error and kicked from my server.

Hey im having an odd issue and I don't think it's yielding a log. My buddy and I are using exact copies of the same pack and are attempting to connect to our dedicated ATM9 server. He's getting in just fine, but I'm getting a
Internal Exception: io.netty.handler.codec.DecoderException: Unknown serializer type 101
Internal Exception: io.netty.handler.codec.DecoderException: Unknown serializer type 101
It's letting me into the server for a very brief moment and then immediately kicking me out. Any ideas? Forge 47.2.20 Minecraft 1.20.1 ATM9 Modpack (with alterations) Connecting to dedicated server Others with the same exact modpack are able to connect with no issues

[19:46:39] [Render thread/ERROR]: Couldn't load 3D model shapes for: [19:46:39] [Render thread/ERROR]: [name]: Unbaked model missing reference to model in blockstate this is the exact error that is causing the issue According to this log at least what version are you playing on? and what version is the MC Server?
Internal Exception: io.netty.handler.codec.DecoderException: Unknown serializer type 101
Internal Exception: io.netty.handler.codec.DecoderException: Unknown serializer type 101
this error means the version of the server and client are mismatched

Hmmmm the version of MC that im running and the version the server running are the same. The pack and the server SHOULD have the same mods as well. I have a buddy who's using the EXACT same pack I am (I even deleted and redownloaded to be sure) and he can get on with no issue.

How did you install the modpack to your server? Are you using something like SparkedHosting or Pebble or something that has a Modpack installer? Usually those modpacks are outdated when they come from the hosting website

I downloaded the server files directly from Curse and installed on a local server.

Have your friend send you his modfolder and replace yours with his and see if that fixes anything
Foresage
ForesageOP•6mo ago
the version of ATM9 is v0.3.0 Roger on it
Alien
Alien•6mo ago
If that fixes it then that means your mods were just outdated
Foresage
ForesageOP•6mo ago
Ok that did not fix it. Same issue

your farmingforblockheads mod requires the "bookshelf" mod, at least 16.0.0 version or higher im not sure how hes joining fine with having outdated mods, weird
