Eftersom jag är en betalande kund anser jag inte att jag ska behöva gå igenom följande text:
If everything was working fine not too long ago, please first check http://www.spotify.com/help/service-status/ and http://twitter.com/SpotifyStatus to see if there are any ongoing issues.
Check that your router allows Spotify in- and outbound and your firewall software allows Spotify in- and outbound.
The following IP ranges should be open on port 4070: 78.31.8.0/21, 193.182.8.0/21.
That number 21 is the prefix length. Please check your router’s manual on how to enter those IP ranges correctly.
Check that Windows (if applicable) firewall allows Spotify in- and outbound
If you have any anti-virus, anti-hack or any other anti-software installed, try to temporarily disable it, just long enough to test your Spotify issue
(Names that come to mind are Norton, McAfee, AVG, etc.)
(On Windows) make sure you start Spotify as admin
Check your router and make sure UPnP is enabled. If it already is, turn it off, then on again
Turn off your router, wait 10 minutes, then turn it back on again
