This problem indicates that Easy365Manager cannot connect to the Easy365Manager licensing service to validate your license.
The license service is hosted on the URL e365mwebsvc.azurewebsites.net and accessed via TCP 443.
You can quickly verify the access by putting the following URL in a browser on the same system where you use Easy365Manager: “e365mwebsvc.azurewebsites.net/api/verify”.
