I have the Spotify Desktop Client on two Linux machines and a Windows 7 computer. In all three instances, the desktop player is not working properly. And by properly, I mean at all.
Yesterday (feb 17), they all started with the offline error 2 code (can't find an internet connection, will try again...). But my internet was working. Now, after clearing the cache and reinstalling on one Linux machine, it won't even log in. I get error code 4 (service temporarily unavailable, try again later). The others are still in offline mode and will not connect.
I have a tablet that works just fine, and my husband's computer is doing the same thing (also Linux).
