I own a server and I want to create an smp for me and my friends. I have fabric 1.19.3 installed along with immersive portals and chisel and bits mod installed. I can join the server and the mods work just fine but whenever I OP myself it kicks me and if I try to join it says 'You were kicked from [SERVER]: Unknown' And in the console it just says I leave. How do I fix this?
