Thanks @chDVRuser. I had already checked the Curl command and all was good on that front. The cabin issue was that the Docker was not active for some reason, but restarting it fixed that issue.
The virtual NAS was able to be resolved when switching to MPEG source vs. HLS. It's odd because the virtual server is all self-contained (same IP address for the Test Channels DVR Server and the Test FuboTV Project Docker).
Crossing my fingers that the Devs ( @tmm1, @maddox and @eric ) consider adding this solution within the server itself vs. a stand-alone source. Granted I know nothing about what that entails, but if possible, would be the most seamless solution outside of HDHR Tuner and TVE (and the 2nd best solution to get Fox and NBC into the server).
Crossing fingers.
