I get this nonsensical error when running on my Azure Cloud instance. On my local machine, everything runs fine, but when trying to use `Microsoft.Data.SqlClient.SqlConnection.Open()` on Azure's instance, it freaks out and gives me this error: `Error HRESULT E_FAIL has been returned from a call to a COM component`.
The lowest level of the stack trace calls: `Microsoft.Data.SqlClient.SqlInternalConnectionTds.GetFedAuthToken(SqlFedAuthInfo fedAuthInfo)`
