Can't add this radio

MOC version: 
moc 5.5.1

I can't add this radio:
to my playlist. I guess it is because the ending is _mp3 and not .mp3
Is there a way to add it?
Thank you.

Actually, it's not the '_mp3' but rather the 'https'.

MOC doesn't currently support secure http connections; it is on the list and is a straight-forward change but requires time to test.

If you're adept at coding, you could add it to the list in files.c:is_url() but it would be at your own risk.

Ok, thank you.
