Connection Bans keep happening for no reason

First off I realize there are other ban threads out there but none match my situation.

Here is what keeps happening to me… I play arena games like Free 4 All and Swat, I play the entire match and finish the round, get to the “Winner Screen” and instead of going to the carnage report it kicks me to the matchmaking lobby… When This happens more than once in a day for me I get tagged with a ban of 3+ hours. It has happened 4 times now… The match is still closing out because I can access the carnage report from the matchmaking lobby, but Halo 5 seems to think I’m quitting the match.

I have a great, stable internet connection with Fiber Optic service and a hard wire into the router… So it’s not a connection problem on my end…

Anyone had similar issues or a suggested solution? This is getting kind of old.
