Error in the Gateway Log folder for Both DC's in the cloud Error [WebClient+<InvokeAsync>d__8`1] System.Net.Http.HttpRequestException: PostAsync failed [requestTypeName=UpsertGatewayMonitoringAlertRequest] ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult, TransportContext& context) at System.Net.Http.HttpClientHandler.GetRequestStreamCallback(IAsyncResult ar) please advise how i can solve this problem.

Hi, yes the fix was to update the agent on the affected machines and the ata server

Can you check if you have any of the following registry keys set on the failing machine or the center? [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL]"DisableRenegoOnServer"=dword:00000001"DisableRenegoOnClient"=dword:00000001 If yes, please try while they are set to 0 (default).

thanks for you reply. the registry keys weren't present on the failing servers and ATA center. However i have tried doing this as i read your article and no luck here -thanks

Are you able to access the console UI from the failing GWs using Internet Explorer without any errors?

Yes i can - I added the ATA console via IE trusted site but i see certificate error in the browser. I installed the certificate for local user and current user.
