Our CMG has been working and recently clients were not able to connect.
Looking at the SMS_CLOUD_PROXYCONNECTOR.log I see [ERROR: Failed to build Http connection 7ed67d18-fd3c-b802-4636-08b96683baac with server CMG.CLOUDAPP.NET:443]
Logged on to [https://portal.azure.com/] go to cloud service and see [Failed starting role Role could not be started. System is initializing.] I restarted the service and same error. Not sure what to do at this point.
