title: Netsuite restlet calls from .Net Api started to give errors
body: <p>I am using token based authentication for calling netsuite restlets from my .Net WebAPIs.
  It has been working well, but since yesterday I started getting this below error on Netsuite sandbox. I don’t see any code change that could have resulted to this. Can anyone point me to the right direction?</p>
  
  <p>System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host </p>
