My SiriusXM app on my box stopped working
My SiriusXM app stopped working and won’t even load (error code 4036) It worked, then stopped for a few weeks. It ran for one day in February and hasn’t worked since. My box is compatible (Xc-1) and I’ve tried all of the remedies, none of which worked. I’m not resetting my box again, because it knocks off the rest of my sign ons.

I first tried the app on Feb 13, 2026 and received the same error. I worked with an xfinity support agent via messaging for more than 90 minutes. We tried various combinations of equipment resets. None of these solved the issue. As a last resort, the agent suggested that I replace the xfinity X1 box. This also did not solve the problem.
I retested today and still get the same error. Other xfinity music apps such as Spotify, iHeart, and Pandora launch successfully.
