WCF HTTPS self-hosted service does not work ("connection to the server was reset")

Question

I have a Self-Hosted (Console App) WCF REST service with the following binding:

• WebMessageEncodingBindingElement
• HttpsTransportBindingElement (ManualAddressing=true, KeepAliveEnabled=true, AllowCookies=false, HostNameComparisonMode=Exact)

This is exposed over an HTTPS URL ("https://mylaptop/myendpoint")

I have a self-signed certificate issued to "mylaptop" that I assign using myServiceHost.Credentials.ServiceCertificate.SetCertificate. The certificate is added successfully, and the ServiceHost opens successfully (no exceptions). If I type "netsh http show servicestate", I can see that there's a successful registration at https://mylaptop/myendpoint with HTTP.SYS

However, when I issue a GET to the endpoint, it doesn't work. It seems like the socket is dropped even before a valid HTTP response is obtained. (FireFox says "connection to the server was reset", IE says "cannot display the webpage", and if I do the request through Fiddler it says "connection was forcibly closed by the remote host").

Everything works fine when I use HTTP instead of HTTPS.

Any idea what could be going wrong in the HTTPS case?

Answer 1

You probably need to use httpcfg.exe to reserve your endpoint with HTTP.SYS correctly with a configured X.509 certificate for SSL. The steps to get it done are documented here.

Answer 2

Or use HttpCfgGui- a much friendlier interface to setting up the server certs w/ HTTP.SYS. This is a must-install on all my servers that do HTTP w/ WCF.

Did you ever solve your problem? I am running into the exact same issue. I implemented a "helloWorld" example with message security and it worked ok. When I switched to transport security I received the same error as you described. I used the following command to bind the service port to a certificate but still am not able to connect from a client after I start the service...

httpcfg set ssl -i 0.0.0.0:9010 -c "My" -h "d97ba741cd0f6c9403cc6683d3e822d5bc2984ab" -f 2
