I have a Respberry Pi 3B+ using Squeezelite and JiveLite. The configuration works using ethernet and easily connects to a remote LMS server.
I have tried to use wifi. I can connect using WPS and I can communicate with the Pi using the browser to access Max2Play.
When JiveLite loads, I only get a short menu of five items. If I select My Music, it attempts to connect to the right server but does not succeed. When I reconfigure ethernet using Max2Play, all seems to work well.
Disabling the firewall has no effect.
I’ve tried to search the forum but cannot seem to find a similar circumstance.
Which Max2Play version do you use? Does your player appear in the LMS web interface when you connect it via WiFi and can you start playback from there?
