I see from your diagnostics that your server logs are reporting the playlist stopped updating:
2023/03/15 21:28:24.711047 [HLS] Couldn't generate stream playlist for ch6073-dTVE-Hulu-798b04472f4e: Playlist has not been updated in 20.5369754s
I also see other problems:
2023/03/15 20:35:06.122375 [TNR] Error during live stream for ch6073 FNC: failed after 33.4457012s: hls: temporary failure while downloading: hls: timeout while waiting for data
that sound like you're having problems reaching the CDN.
Troubleshooting on your DVR reports:

Changing the DNS on your DVR to be the DNS servers provided by your ISP may yield better results.
