Send GET HTTPS request but get 403 forbidden response, why?

Question

Below is the URL I send to the WS after the handshake is done

    \"https://ekp.truefriend.com/COVIWeb/gate/AutoAuthentication.aspx?UserID=DP0001&BackUrl         


        

Answer 1

Your question contains the answer. Upon trying to access the URL you specified in Chrome, you get a big red warning "The site's security certificate is not trusted!". While you can manually override in a browser and ignore the warning, your code treats this as a security problem and a dead end. It even recommends you contact the server administrator.

If you are the server's admin, change the SSL cert to a valid one. if not, ask the admin to do it. Failing that, try accessing the HTTP (non-SSL) version of the site.
