Network Protocol Error connecting 1.21.5 client to 1.21.4 server

Client log is attached. Normal 1.21.5 can connect so idk which mod is breaking it. My normal culprits of ViaFabricPlus and Essential arent it - already tested removing those.

Using Prism launcher I just copied the instance and then updated MC version and mods. It loads up just fine to the server selection screen.

I do have console access but the server just shows as if Im connecting and disconnecting normally.

The attached log is from the client loading into my server. This pic is what happens when I try to load into hypixel. Single player works fine
