Hello,
The error I am getting using the Android app for Subsonic (the official one, not a third party app) is `A network error occurred. Retrying..`.
Using the webinterface, everything works, and after manually portforwarding port 4040 and verifying that the port is open and creating my own custom url (which responds succesfully), the app does not work when I try to connect to my server.
I have of course bought premium. I hope I am correct in assuming that the username and password needed are the ones used for your account in the web interface (the one you had to create yourself).
Help would be much appreciated.
