A ban for nothing?

Link of the video demonstrating what I mean:

Before I immediately got this “ban” on the game, I joined a friend’s invite to play the game, and I haven’t started the game yet. Once entering I am greeted with this and I am left to not play at all for 24 hours.
Just for the clarification, I’ve not done anything that determines a ban such as quitting a game and etc.
This is an ongoing error for both me and my cousin since we keep getting on and get this error for doing nothing. If it’s a network problem, then it should be solved ASAP. This is tiring me and my cousin for a problem that we can’t solve.

Hey OP, please use the ban thread pinned at the top of the forums for any queries on matchmaking bans
