Volumio2 - music library works, but no streaming sites

In the old volumio I had a couple of iheart radio streams set up for local radio stations:

I’ve added the stream to volumio as a favourtie web strea:

[ { "service": "webradio", "name": "ZM", "uri": "http://radionetwork-iheart-ice.streamguys1.com/zmihr.aac" } ]

But it never seems to execute the stream.

Hmm just went to my volumio machine to play a stream to grab the logs, and clicking browse just brings up an empty screen (has headers/footers etc, but no details. Seems to happen fairly often.

Here is the log when I started playback:

Also I enabled the spotify plugin, added credentials, but it never shows up on the browse menu.
