Hi,

We are trying to build an internal AWS CloudWatch Driver that uses the AWS SDK Library. The new driver is only required to return the list of alarms that are currently present on the CloudWatch Alarms List. The following code should be retrieving the list of alarms:

However, we keep getting the following exception in the logs every time we try to retrieve the alarms.

Note that we use the following DLLs in the solution:

• AWSSDK.Core.dll
• AWSSDK.CloudWatch.dll

Amazon.Runtime.AmazonServiceException: A WebException with status ConnectFailure was thrown. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 52.94.50.138:443

Is this related to the security config of the DMA (TLS 1.2)?

Thanks,
