hello,
my client code communicates with a web service through a https connection.
the code has a stub derived from SoapHttpClientProtocol. It also sets a
certificate policy handler that allows everything:
class CertificatePolicy : ICertificatePolicy
{
public bool CheckValidationResult(ServicePoint servicepoint,
X509Certificate certificate, WebRequest request, int problem) { return
true; }
}
but some users reported the below exception when the client code calls
Invoke on the stub.
System.Net.WebException: The underlying connection was closed: Could not
establish secure channel for SSL/TLS. ---> System.IO.IOException: Unable to
read data from the transport connection. ---> System.IO.IOException: Unable
to read data from the transport connection. --->
System.Net.Sockets.SocketException: An existing connection was forcibly
closed by the remote host

at
System.Web.Services.Protocols.HttpWebClientProtoco l.GetWebResponse(WebReques
t request)
at System.Web.Services.Protocols.SoapHttpClientProtoc ol.Invoke(String
methodName, Object[] parameters)
...
I asked one of the users who have this problem to navigate to the web
service url in IE browser, and it worked, and showed the help page for the
service with the list of methods, etc. No certificate warnings were
displayed, nothing.
I am confused.
Could someone help?
thank you

The message you are getting is misleading you.
I got the same problem days ago, it appears that the web methods kicks an
exception, and your code is not handling it properly.
I guess your event view has some weird message as well on the server.
Solution is to trace down the exception on the web server and fix it.
Hope this helps.

thank you for your response.
this does not explain why the other users are able to communicate with the
web service successfully, and this particular one cannot. All requests fail
for this particular user.
