Whenever I join my modded server with the same mods as my client I get the error stated in the title. I don't know what to do, I have tried deleting my client's config folders as well as the mod configs on the server, deleted a few mods I could do without and it still gives me the error and kicks me out of the server after like 3 seconds of joining. This only happens on multiplayer and not singleplayer.
