Access web service via HTTPS using proxy class

Our game will be running behind a client's firewall and must access our server for various reasons. I am trying to create a connection between game and service using a proxy class. The connection works perfectly when I access the web service using HTTP, but when using HTTPS I get the following error message in Unity:

and

Anyone know if this is a Unity/Mono "feature" or do I need to "activate" HTTPS somehow?

Thanks,

I don't think mono 1.2.5 has HTTPS (fully) implemented.
Especially in case of the Webplayer it wouldn't work anymore anyway (if you are using that) cause System.Environment is blocked in webplayers (as is System.IO and other local access paths)

 

Thanks dreamora, that's what I was afraid of.
And just for clarification, we are developing the game as a standalone application, not a web app.

I experience the same on Vista w. Unity 2.6.1f.

 

If you just want to get access working (Note! Without any security checks!), here is a way around it:

Code (csharp):

1. ----
2.         // KRO: Currently .net deprecated approach to have https support in unity w. old mono version
3.         private class DummyCertificatePolicy : ICertificatePolicy
4.         {
5.             public DummyCertificatePolicy()
6.             {
7.                 ServicePointManager.CertificatePolicy = this;
8.             }
9.  
10.             #region ICertificatePolicy Members
11.  
12.             public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem)
13.             {
14.                 return true;
15.             }
16.  
17.             #endregion
18.         }
19.  
20. ----

Just make an instance of above dummy class before you call WebRequest.Create.

Also note that above is a deprecated approach in newer .net platforms.
