Mobile browser on same network can not connect to Spotify

[s-cotton]

I have the interface up and running on a rPi2, and I am passing through a virtualhost with apache proxypass from my home web server to the Mopidy web port. I can access the interface without issue, and was able to connect spotify from a browser on a desktop on the LAN. Works as expected there using the virtualhost address, mp.domainname.com (Ports 6680, 6681 and 6600 have been mapped on the router to forward through to the rPi as well).

I tried to connect in my Android phone so that I could control the system from there, but upon authenticating the spotify application, I end up at a blank screen on your domain, at the spotmop.php file. I was connected via WiFi at that point, so I also tried doing it over my 4G connection with the same results.

Am I missing a piece of the setup here? Thanks!

Hmm, that would suggest a lack of browser support for HTML5 window.postMessage functionality (see specs). What browser and version are you using on your Android phone? Do you have javascript disabled on your phone or browser?

Please note that in order to achieve this outside of the network your RaspberryPi is on you will typically need to have a fixed IP address.

Fixed IP is resolved with Dynamic DNS and the Virtualhost. Ive been able to use it fine if there is another user (the desktop user) who has signed into spotify and I uncheck "Connect with Spotify" in the mobile device, but only if that desktop user has already started music playing, otherwise I get the "Connect with Spotify" error message in the top pane of the application. At that point, I try to connect with spotify and I get the white screen.

Quick question - what version of Spotmop are you running?
