Online source... blank !

Well, I'm using Serviio for a couple of years now, and it seems that I can't display online sources anymore...
I don't have any problem streaming music/video from computer to TV with Serviio.
I tried to add some online contents such as Twitch for video, and TuneIn for music. I installed the according plugins into the HD/Library/Application Support/Serviio/plugin folder and even restarted Serviio.
One of the links entered is https://tunein.com/radio/Radio-NARITA-837-s238381/
I selected 'Audio', and 'Web Resource'
The link works with my web browser, but Serviio URL stream check say the link is not valid or not currently available...

On TV, I go to Audio => Online Content => nothing appears....

Same goes with videos, where I tried with a Twitch channel ('Video' and Web resource)...
Is there something I'm missing ???
Thanks !

Serviio v1.10.1, iMac with Mojave 10.14.3, TV Toshiba.

It's possible that the plugin is broken.

Will have a look if I find the time.

I've updated the plugin, try to get the new version.

Thanks !
I have the list now, but streams don't play : some give a message 'not compatible with the player', others play 2 secondes then stop...
Oh well....
