Problem :

I really thought that I had this issue fixed, but it was just disguised before.

I have the WCF service hosted in my IIS 7 using HTTPS. When I try to browse to this site in the Internet Explorer, it works like a charm, As I have already added the certificate to the local root certificate authority store.

I want to developing on 1 machine, so the client and server are the same machine. The certificate is self-signed directly from the IIS 7 management snap in.

But I continually get below error now:

Could not establish trust relationship for the SSL/TLS secure channel with authority.

Whenever I try to call it from the client console.

I manually gave myself the permissions and network service to my certificate, using findprivatekey and also using cacls.exe.

I just tried to connect it to the service using SOAPUI, and that works, so that must be an issue in my client application, which is the code based on what used to work with http.

Where else should I look as I am completely exhausted I tried all possibilities as to why I am unable to connect?

Solution :

A one line solution to your problem. Please add below code anywhere before calling the server on your client side:

System.Net.ServicePointManager.ServerCertificateValidationCallback += delegate { return true; };

This must only be used for the testing purposes as the client will skip SSL/TLS security checks.
