We are currently in process of migrating our application to cloud environment.

In the application, we are using ComponentSpace dll to verify Artifact returned from CorpPass site. The method SendRequestReceiveResponse() used to process the request and the passing parameters are WebRequest and XMLElement. Refer below.

public static XmlElement SendRequestReceiveResponse(WebRequest webRequest, XmlElement artifactResolve);

So for it is working as expected since we using the direct CorpPass URL to generate web request and passing to the above method. In cloud environment, we should not use the CorpPass URL directly. Instead, we host the CorpPass URL in azure server and calling the URL at backend using WEB API.

When we pass the WEB API URL to the SendRequestReceiveResponse() which is inside ComponentSpace dll, it is throwing the following error.

ComponentSpace.SAML2.Exceptions.SAMLBindingException: Failed to send/receive SAML request/response over SOAP. ---> 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

For some reason, the other end is closing the connection ("An existing connection was forcibly closed by the remote host").

This issue isn't at the SAML protocol level. Instead, a transport connection cannot be made to the remote host.

It's difficult to determine the reason without detailed information from the remote host.

It's possible this is failing during the SSL handshake phase but someone needs to check the remote host logs to determine exactly why they're closing the connection
