New Stream URL fails

[ArbieF]

We have been streaming successfully from a url in this format:

https://stream.xxxradio.online:8030/APM

They now want to change it to this format but I can’t get it to work in Radioboss:

https://xxx-encompass.akamaized.net/cmaf/live/2121575/xxx-edm/master.m3u8

(sorry the links are not public so I masked them a bit)
In the back and forth between the customer service and technical people they said:
“This manifest file defines the bitrate (128Kbps) and container format (MP4a) and references a child manifest file, which is currently: Audio1_1.m3u8. The Audio1_1.m3u8 manifest file is updated every 6 seconds and contains a list of 11 x 6 second long segments of aac audio in an MP4 file.”
“The parent/child m3u8 manifests are used to support failover and are part of the HLS specification, but I’m thinking that if the affiliates receiver systems is unable to support parent/child references then it might be treating Audio1_1.m3u8 as an audio segment, and failing when attempting to play it back.”
Gibberish to me. What I see in the log is: Unable to play! Error code 41 (unsupported file format).
What do I tell them I can support?
FYI: I attempted to see what kind of AAC files I can support by converting an mp3 file to aac in radioboss. It failed code 2. A problem with FFmpeg?

Forgot to mention: Both URLs play fine in a Chrome browser but don't work properly in the web playlist tab in Radioboss

This does look like HLS streaming format, and this RadioBOSS should be able to play - if you use Playlist->Add URL command.

But what the internal web browser could do, is a different thing.

If you use the "Add URL" command will this URL play?
