Error message when trying to connect to Max through Xfinity provider

I have been trying to access Max through my Xfinity subscription all day and I am receiving an error message. I keep getting the prompt to sign in and when I do so, I get the following error:

"response": "failure",
    "code": 5116,
    "status": 401,
    "detail": "unauthorizedInvalid authentication response from Synacor",
    "locale": "en-US",
    "title": "Partner Authentication error",
    "message": "Unable to complete partner authentication process. Please contact support."

This is happening whether I try to access Max directly through my cable box, the Max app on my Amazon fire stick or the Max app on my iPad.

This is extremely frustrating. Please help.
