cannot connect to icloud library

All of a sudden my itunes says I can't connect to icloud library so I can't add anything from Apple Music to it. I turned off icloud library and tried to turn it back on (one of the suggestions from the web) but now it says genius can't connect, unknown error 11111. What do I do to get connected back to icloud library? When I go back to my iphone music library, everything is still there including Apple Music.
