Banned for no reason

I was playing that new game mode, fiesta or something , for the first time, when afterwards it backed me out to the lobby and said I was banned for 30 minutes. I would love to know why and if this happens to anyone else.

you have 3 DNF’s today… It sometimes takes an extra game for the game to detect ban you for your DNF’s.

You were banned for any one of the following: quitting, idling, or griefing. There is a ban thread in the Halo 5 support section. Have a go there.

PS. Been and You’re.

There is a ban permathread located at the top of the Halo 5 forums. I’m pretty sure you’re supposed to use that.

Like the others have said, feel free to use the pinned thread in the H5GS section.
