Qnap 'Connection Lost' with m3u list

I running Channels on my Qnap and until yesterday everything was fine.
No matter where I open the app, including on a separate desktop channels server I installed, my m3u will no longer play any channel. The EPG and channel list loads no problem.
The same m3u link works just fine in tvmate or other apps, and my connection to my qnap is perfectly fine. I've tried creating and loading a new m3u source, restarted the qnap, reset router, ect.

Any idea what the issue is? Also, I'm not sure how to run a log, so please advise.

What is in your log?

Bring up the admin screen on a computer browser. Click on the upper menu: Support > Logs. Then scroll through the log, and see if you can pick out anything that looks hinky.

You also could do Support > Troubleshooting, and see if anything is wrong there. You want green checkmarks on everything there.
