Tablo connect on fire stick not linking to home Tablo

Tablo connect on my fire stick was working fine away from home but now will not connect. I returned the firestick to my home network, reloaded Tablo (not preview), reset the Tablo (blue button), reset modem and router, rentered the router firewall settings.
None of that has worked. Any ideas?

Do you still have an active subscription? Tablo Connect requires an active subscription to work.

Yes, subscription is active. Remote works fine on other devices (iPad, smartphone)
