An error has occured

[Natecher]

I have been receiving "an error has occured" every time I've tried to listen on my iPad and iPhone 5; I am not able to search or listen to any music that has not been synced prior on my devices. This has been occurring off and on the past few weeks but over the past two days has not worked at all. Went to spotify.com and unsynced all devices and reinstalled in both devices and still nothing is working. Photo attached is what I get when searching.
