If in Visual studio, it should prompt you with if trust it, if you click yes, then it should work. What IDE are you using?

I am facing a similar issue, but I am getting this error as I’m attempting to create the generated proxy for services consumption. Therefore, modifying client code serves me no purpose. How does one resolve this issue prior to runtime?

If the target production certificate is valid. you don’t have to use this method.

Try this:
System.Net.ServicePointManager.ServerCertificateValidationCallback = ((sender, certificate, chain, sslPolicyErrors) => true);

Before you make any calls.

the web serivice i have to consume is on SSL and the service provider has provided us test certificates..
I created a wrapper in ASMX to access this service, ASMX wrapper is required coz other app like Visual file can’t directly access WCF..
when i run my ASMX wrapper from Asp.net Dev enviroment it works file.. but when i host this ASMX wrapper on IIS i started getting error, as
Could not establish secure channel for SSL/TLS with authority ‘uat-portal.swiftcover.com
even i call the code as you have specified to accept all certificates.. plz help

If you can set a breakpoint within RemoteCertificateValidate method at the client, you can find out what the actual error is by examining the values of the SslPolicyErrors. Let us know how it goes. Good luck.

@Harjeet Chandwani
I’d suggest you post the error details here and find out the URL from your client app.config. This is really SSL certificate related error message, I am still suspecting you are using an https url for the web service.

Thanks for the reply. We are not using any certificate on any of the server related to this API. This problem is only coming on production server but it works fine on pre production servers and we have not installed any certificate any where.

@Harjeet Chandwani
Does your production server as the VALID certificate?
Does the SSL certificate subject allows the domain name that you host your webservice?
Normally, you may find the domain name in the subject field of your certificate.
