Blink sync module disconnected after update and cannot reconnect via Xfinity

Suddenly for some reason not able to reconnect Blink via Xfinity after several years of working with no problems. This is the second time that this has happened in a couple of months following Blink firmware updates. Infinity was able to reconnect for me the previous time.
Steps we have taken:
- reset xfinity modem - multiple times
- reset blink sync module - multiple times
- checked / updated blink firmware
- connected blink to hotspot which worked confirming Blink functional
- disabled 5 g in xfinity wifi setting but still will not connect
- manually added Blink Mac address in router settings… still will not connect

Thank you,
