I have a asp.net mvc website developed in .NET framework 4.7. getting connection issue from hosted website. can you please help

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

推荐答案

在调试时，我通常会遇到此错误，但是如果部署此错误，它将消失.
为了进行调试，请在调用外部服务之前添加以下行.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

I usually face this error while debugging, but if you deploy this it will disappear.
For debugging purpose, add following lines before calling external services.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
