ATA Services suddenly failing to start.

Hi Guys,

 

After my DCs have recently rebooted, the ATA lightwieght gateway agent on them is failing to start.

 

Looking at the error log is see the following error repeatedly:

 

4832 4   Error [WebClient+<InvokeAsync>d__8`1] System.Net.Http.HttpRequestException: PostAsync failed [requestTypeName=UpsertGatewayMonitoringAlertRequest] ---> System.Net.Http.HttpRequestException: Error while copying content to a stream. ---> System.IO.IOException: Unable to read data from the transport connection: The connection was closed

 

Anyone have any suggestions as to what might be causing this?

 

Thanks

David

    Looks like the DCs lost communication with the center machine.

    Are you able to browse the Console UI using Internet Explorer from these machines?
