This error message means internet connection is being lost. It may only be for a moment but when an error message references call failed, thats saying that the call that your computer is making to our database has been interrupted. RevolutionEHR is constantly sending information back and forth between your computer(s) and our servers unlike a normal html website where it loads a page and then just sits there until you click something else and it load another page. So any interruption in connection to our servers is going to result in an error message. First thing you’ll want to do is reset your modem and router. If that doesnt help, then you should contact your internet service provider and tell them exactly what you’re experiencing.
