Don't know what happened, creative cloud app just can't connect to server since 2 days ago. I have never set any firewall and it is turned off. Quitting and relaunch doesn't solve the problem. Please help.
I have been getting this same error on and off and its been making me crazy. I fixed it by going into my Avast Cleanup app and "waking up" all of the Adobe processes that I long ago put to sleep. It fixed the problem immediatly! Hope this is helpful to someone.
