Connection to Dynamics 365 CE from Windows Server 2016

Hi friends,

I don't usually ask questions here, but have encountered an issue that never had before. We have a very simple C# Console application that connects to a Dynamics 365 environment that is running without any issues on Windows 10 and Windows Server 2012 R2. The code that we are using is shown below.

private CrmServiceClient Connect(string userName, string password, string orgName, string region = "North America")
{
   ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
   CrmServiceClient conn = new CrmServiceClient(userName, ConvertToSecureString(password), region, orgName, isOffice365: true);
   
   return conn;
}

Like I said this works in Windows 10 and Windows Server 2012 R2, so there are no issues with the code, credentials, orgName or region that are being passed to the function.

After executing the function, the returned CrmServiceClient has the following information:

ConnectedOrgFriendlyName: null

ConnectedOrgId: {00000000-0000-0000-0000-000000000000}

IsReady: false
LastCrmError: Unable to Login to Dynamics CRM

I have tried this with various versions of the SDK (8.2, 9.0) and am getting the same results. The target environment is 9.0, but have also tried with a target 8.2 environment.

Internet Explorer Enhanced Security Configuration has also been turned off.

Any help would be appreciated.

Thanks.
