Unable to join certain servers despite no restrictions/problems with my acc

So im currently trying to join a Youtubers discord on my discord account and for some strange reason, no matter if i send it via a inv from an alt account (Which can join it for some strange reason), join through a link inv or through a code, it kicks me right out and acts like i never joined the server in the first place. It happened both before and after joining with my alt, so i dont understand what seems to be the problem
