 Recently network team disabled TLS 1.0 and Enabled 1.1 on server for testing. Now website broken and getting below error.

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

 Is there any way to fix in configuration settings and website work.

Latest .net framework 4.7 installed on the server. Please give me some suggestions.

To enable TLS 1.1 I added following code line inside the module:

Page_Load(object sender, EventArgs e)
{
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;
//rest of your code
}
