Remote pair FAIL will cost Tablo lifetime subscription

So I get to my device and discover it’s none of the above. After kinda working for 3 weeks Tablo reports this error:

What am I supposed to do? Enroll in networking course, open a support ticket? I didn’t post the “local port numbers” in the event that might not be a wise thing to do over an openly viewed forum?

I’ve setup port forwarding for webcams in Airport Express utility before but I dunno where to begin with this???

EDIT to add - fortunately, I found this discussion - Port Mapping / Forwarding

Unchecking and rechecking Remote Access appears to have corrected the issue.
