Connect to https:// webservice in asp.net app

I have an ASP.NET website that is contacting a webservice. Everything works fine connecting via http but when I try https:// it can't connect. I don't seem to get any error from the website and the webservice logs show nothing, meaning nothing has connected to it.

I can connect to my https:// webservice from a site like soapclient.com and request information, so the webservice and ports are working.

Is there anything special I should be doing in order to connect to a https:// webservice over a normal http:// one in .NET? All I am doing at the moment is changing the URL it is connecting to to my secure one instead.

I am using ASP.NET 2, IIS7

Thanks in advance.

EDIT: Just found the actual error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel - Which in my eyes tells me I haven't added my self signed certificate to the installed certs on the server ... but I have ...

You need to add your self-signed certificate under Trusted Root Certificate Authorities in the Local Computer store of the server running the ASP.NET website.

Export the certificate from the webservice server as a .cer file, and copy it to the server running the ASP.NET website. Then, on that server:

  1. Double-click the .cer file and Install Certificate
  2. In the wizard, choose the store as the Local Computer folder under Trusted Root Certificate Authorities.
  3. You might have to restart IIS, or the server

There are some good instructions towards the bottom of this page, under "Installing the self-signed certificate on client computers": http://webhelp.esri.com/arcgisserver/9.3/dotNET/index.htm#setting_up_ssl.htm

It looks like your client encounters a certificate validation error, because your server certificate is self-signed.

Try including the following line (C#) in your web site code, before calling the web service. This will tell .NET to ignore all certificate validation errors: 

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => { return true; };

This should obviously not be used in a production environment :)
