Not letting me in BA anymore

I’m online my WiFi is On and working but it’s not letting me into the BA all of a sudden it keeps saying no match found and it won’t let me in anymore when it always would before is the BA not working right now or what

I don’t have any issues here, I just tried.

DM me your dq account email address and I will try to log in.

It was doing the same for me but then I tried to upload my account to DQ cloud and it said " You must update your app to upload", so I updated it and then I could upload and go to the Arena.
