Xfinity XFi keeps kicking me out

Trying to conncect my new xfi pods.  I log into my Xfinity XFi app, it's says "checking some things", than says "sorry we're having some trouble".  I've been on the phone with techs, had techs out to house, reset modem, uninstalled and reinstalled app 20 times.  Same thing.  Very frustrating
