Live TV getting 'Plex server unavailable', using PLEX app on Firestick, Tivo Stream4k & tablet

It was working about a week ago. Now on Live TV & Dvr I have an orange triangle and it errors: ‘Plex server unavailable’. This happens when using the PLEX client app on Firestick, Tivo Stream 4k & Samsung tablet (they play other media libraries fine).
But Live TV works using the Win Plex client app and ALL web browsers (the HDhomerun app on the Tivo works fine as well). They were all working about a week ago before recent (at least 2) PMS updates. I tried removing/re-adding tuner, powering it (and router) off/on, no help. I am out of ideas, can I get some help?

I had to completely logout of Plex on all streaming devices. Then sign back in again and re-link each one at plex.tv/link to get Live TV to respond correctly, no longer showing the orange triangle. This included 2 Firesticks and 1 Tivo Stream 4k. It would be nice to know what caused this!
