HTTPS Connections Timeout with Decryption Enabled
Problem: Client Application Cannot Reach HTTPS Site when Fiddler Classic is configured to decrypt HTTPS traffic.
This issue occurs on Windows Vista or later.
Solution 1: Customize Fiddler Classic Rules to force SSLv3 handshake
Click Rules > Customize Rules.
-
Add this code to the OnBeforeRequest method (where "HTTPSsite.com" is the hostname of the destination server):
if (oSession.HTTPMethodIs("CONNECT") && oSession.HostnameIs("HTTPSSite.com")) { oSession["x-OverrideSslProtocols"] = "ssl3"; FiddlerApplication.Log.LogString("Legacy compat applied for inbound request to HTTPSSite.com"); }
Solution 2: Modify .NET application to force SSLv3 handshake
Use this code in your .NET application:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
