I use Fiddler quite frequently for decoding HTTPS traffic, but it stopped working after I got the Anniversary upgrade installed and I'm not able to figure out what's wrong. It looks like the problem occurs on SSL "Version: 3.3 (TLS/1.2)" - the Fiddler HTTPS options dialog doesn't offer TLS 1.2 in supported protocols: "Select the HTTPS protocol versions allowable for server connections. Valid tokens are: <client>; ssl2; ssl3; tls1.0" and our application servers support just latest TLS 1.2 version. The connection from my C# application to the server works until I enable Fiddler capture with HTTPS decryption. I can see the handshake in Fiddler, but not the real request - I just get "Could not establish secure channel for SSL/TLS with authority" in my C# application instead.
Any idea what could I try to get TLS 1.2 capture + decryption working in Fiddler again?
