I get following error while working with REST API and i do following code change to resolve this issue.
The underlying connection was closed: An unexpected error occurred on a receive.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
at System.Net.Sockets.NetworkStream.Read(Byte buffer, Int32 offset, Int32 size)
To resolve above error add following properties to webrequest object
HttpWebRequest webRequest = (HttpWebRequest) base.GetWebRequest(uri);
webRequest.KeepAlive = false; webRequest.ProtocolVersion=HttpVersion.Version10;
Happy Coding !!
