How do you use WWW with HTTPS? I'm getting an SSLHandshakeException on Android

“javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.”

Any idea? Our code works just fine on our test server using http. I can’t find any reference in the Unity docs, except that iPhone supports https…

Specifically, we are using our own certificate, not a certificate authority.
