rdk-03036 error on cable box

for the past 2 weeks our cable box kept becoming unresponsive and so we had a tech come and install a new one.

It worked OK for about a week, but today it just goes to an error rdk-03036.

We only have the single cable box in the house.

When I go online to resend the single or restart the box it says its unresponsive.

All cables are tight.

We also tried rebooting our internet/wifi router.

I am at my witts end and ready to bring all the equipment to a center and just cancel it.
