[FFmpeg-user] m3u8 download has no audio track

I'm attempting to download video from nebula (https://nebula.tv) for
offline viewing. I use this command line:

ffmpeg -i"http://example.com/video_url.m3u8"  -c copy -bsf:a aac_adtstoasc "output.mp4"

(taken fromhttps://windowsloop.com/download-m3u8-video-with-ffmpeg/).

This has worked in the past, but lately from Nebula, I get an output
file with no audio track, according to ffplay, and also vlc and mplayer.

Suggestions? What information can I post that will help to debug this.

Note: I am a paying Nebula subscriber and do not pirate their content.
I just want to be able to watch it offline, notably on planes.

Thanks for any assistance.
