server access denied on xfinity app

I can log in on the pc, but the iphone i get the following message "Access Denied, you dont have permission to access http://login.xfinity.com/login on this server reference #18.2659c817.1772486015.1487376e

https://errors.edgesuite.net/18.2659c817.1772486015.1487376e

ive tried clearing cookies, reinstalling app, clearing all browser histories, no effect

The one time I did get ahold of a real person from xfinity (which is near impossible), They were able to "invite" me into the app manually, but after that session, it reverted back to the same access denied error

what do i do now?
