Bug Description

The server just kicks me out when trying to join on a 1.20.4 server when I'm trying to join on a 1.20.1 version. I wouldn't be putting this issue in as I could just play on 1.20.4 but since I have client side mods that are only updated to 1.20.1, I'm forced to play on 1.20.1.

Steps to Reproduce

1. Have a server running Spigot/Paper 1.20.4
2. Have ViaVersion, ViaBackwards, ViaRewind on latest versions
3. Launch mc with any launcher in 1.20.1 (in my case I used feather)
4. Join the server with the version 1.20.4
5. Get kicked with the error in the ss below
   

Expected Behavior

Being able to join my 1.20.4 server when I'm playing on 1.20.1

Additional Server Info

When using the latest snapshots, I get this message

The client side mods I'm using are listed here. Im pretty sure the plugins are listed in the dump (hopefully?) but if you need a list, I'll make a pastebin with a list of my plugins.

Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

Please update all Via* plugins from https://ci.viaversion.com/. In case the issue still persists send the new dump and the issue will be reopened

The invalid payload register is caused by a third-party mod. also because you use jdk 21.0.1 to run the 1.20.4 server, paper is recommended over spigot.

Alr thanks, also im using spigot over paper as i need the chunk bans that i use to work but thanks!

I have the same problem, but I use Waterfall proxy, PandaSpigot lobby and Purpur server, all on the latest version. But with client 1.20.x there is a version error.

When trying to go from the lobby to the server (which is on 1.20.4) I get this error. I've already tried using ViaBackward, ViaRewind, VersionControl... everything...

[Kichura]

@mateuscolli this is an bungeecord-related issue but is currently being addressed by PR #3534.

[mateuscolli]

So in my case, it's something with Waterfall right?

yes, you can attempt to solve it by running viaversion on spigot/paper itself or by moving to velocity.

[mateuscolli]

viaversion is already in my proxy... I'll try to switch to velocity then
