I have installed Volumio 2, in a raspberry pi 3 (I have also tested in pi 2), and it seems that any function requiring internet access is not working. Examples, I cannot install plugins (when I press PLUGINS it displays the pluggins screens for a second and then directly returns back to volumio.local/playback), WEB radio is not working and SYSTEM/check updates is not responsive.
Moreover, when I play music from Browse/Music Labrary/Nas etc, it is fine. However, when I press Browse/Albums, after a second it jumps to volumio.local/playback (similarly to PLUGINS example above. )
I have checked both wired and wireless connection without success.
