[misterquestions]

This issue occurs when only Valkyrien Skies, addons, and the mod I have specified are installed and no other mods

• [x] I have tested this issue and it occurs with only Valkyrien Skies, addons, and the mod I have specified

Minecraft Version

1.20.x

Mod Loader

Fabric

Issue description

When using a proxy server like Velocity, it seems to break network not allowing players to move .

Issue reproduction

Create a server for Velocity proxy and add a Fabric target server, when joining you shouldn't be able to move.

Possibly caused by the network moddifications VS2 adds.

This also happens on forge 1.18.2: I can join the lobby (paper 1.20.4), but cant move nor be moved (pushed, fall, ...), but can be tpt. Switching to another server straight up doesnt work (neither paper nor forge, tested with paper versions 1.20.4, 1.20.1, 1.16.5 and forge 40.2.21; forge error is attached): Im stuck in "negotiating" screen from Forge Client Reset Packet (FCRP from now). I dont have Clockwork installed, but Create interactive and "some" other mods. None of them are on the incompatibility list, besides create. The modpack does run perfecty fine without those to mods (despite the 7k lines of errors on server startup).

I tryed it with 1.19.2 and I also cant move, but I can connect to other paper servers. I dont want to make a 1.19.2 modded Server right now, but if I remember correctly it worked last time I tryed.

ok, slight correction: I removed the error since it was thrown by proxy compatible forge being configured incorrectly, but I dont want to change anything about the server now, since im happy it works.
