Can't join any server

 A friend tried to invite me to a private server that they made and no invite seemed to work for, it worked for other people so it's not the link. They have checked the ban list and there is nobody banned on that server(it was made a few hours ago) and then I noticed something odd, I can't join any server and no invite link works for me.

 For transparency I will admit that I was banned from discord in the past during a period of my life that I look down upon with shame and no longer stand by what I said and believed then, maybe it has something to do with that?
