As of today I cannot access the Radio Paradise FLAC streams any more on my RPi based Volumio box (latest version) and get a brief message flash up about a CA cert error, it doesn’t appear long enough for me to read it properly unfortunately. The various AAC and MP3 streams all work perfectly.
I can access the URL https://stream.radioparadise.com/flac via a browser in Windows 10 without problem, and if I click on the padlock in the browser I see that the cert is valid until 11th November 2021, so I’m puzzled as to what the problem is here. Here is the output of the curl command from the box itself …
volumio@volumio:~$ sudo curl https://stream.radioparadise.com/flac
curl: (60) SSL certificate problem: certificate has expired
