Error code XRE-03121

Started getting error code XRE-0321 on a XiD-P about a month ago daily so I swapped the box out at a retail location. The new box has not fixed the error code from happening.

I am receiving the error on all stations when it occurs every day at different hours of the day.

Restarting the box and system refresh within the xfinity system do not fix the error. Hard resetting the box by removing power for a few minutes then powering back on doesn't fix the issue. The only fix that has been working is using the troubleshooting assistant which fixes the issue but takes hours then once working the error code will come back randomly a few hours to a day later. 

This issue only pertains to this box/tv location and the other two boxes in the house do not have this issue.

Hellouser_sgc7om! Thanks so much for bringing this ongoing issue to our attention here on our Xfinity Forums. I'm sorry that you keep seeing this error even after taking the correct steps to troubleshoot and issue as well as going out of your way to exchange the cable box. Thank you for putting so much effort into finding the solution. I wish it were an easier fix for us. 

Based on the details I was able to find for the error XRE-03121 we may need to set up a repair appointment.

The XRE error usually indicates an issue with connecting to the X1 platform, which is why we ask to reset the cable box and check the connections since a simple loose cable can create all the trouble. Since you have taken those steps already it could be that the box is not receiving the correct signal needed to reach the platform. 

 

You mentioned the trouble started about a month ago. Was the cable box moved to a new room or location in your home by chance?
