I left a server and when I tried to join it says I'm banned when I'm not.

I left my friend's server because something happened. Later, I asked a friend to send me an invite link but it said I was banned even though my friend checked logs and ban list and I wasn't banned. I’ve been sent 10+ invite links and none of them are working. I've also tried creating an alt account which didn't work. I unlinked my phone number which didn't work either. My friend also unbanned everyone and then tried to invite me which didn't work as well. Someone help please.
