Prerolls Crash Firestick Users, Roku and others OK

Server Version#: 1.25.5.5492
Player Version#: ?

My original NAS took a dive back in November, so I replaced it with a QNAP. In that window of time, I had disabled Prerolls. Now that I’m back up and running, I’m looking to reintroduce them but I am encountering issues.

Tests that work:
Roku - local
Plex Web - local and over VPN
Android Phone - local and over cellular

Tests that do not:
Any FireTV app - remote

Logs captured a few moments after a failed attempt:
