What's the issue you encountered?

Opped players on my fabric server are being kicked. The server is setup as a proxy (plain velocity proxy and fabric server).

When opped the player gets kicked immediately and cannot rejoin. Upon de-opping them, they can rejoin as usual. The server nor the client crash mind you. Just the client gets disconnected.

How can the issue be reproduced?

I'm running a fabric 1.21.4 server with the following mods on server and client:

• SereneSeasons 1.21.4-10.4.0.6
• GlitchCore 1.21.4-2.3.0.4
• FabricProxyLite 2.9.0
• Fabric API 0.119.3

Additional information

I'm happy to test fixes on my server, it's a live server so I'd like this to be addressed at your earliest convivence although I do understand what maintaining mods is like, thanks!
