Fiddler is not showing HTTPS traffic - https

Question

I enabled "Decrypt HTTPS traffic" and "Ignore server certificate errors" in Fiddler but the traffic of one website is not being showed.
This is the error that Fiddler is returning:
[Fiddler] The connection to '...' failed. System.Security.SecurityException Failed to negotiate HTTPS
connection with server.fiddler.network.https> HTTPS handshake to
... failed. System.IO.IOException Received an unexpected EOF
or 0 bytes from the transport stream.
I remember that I could ignore this error in Fiddler script, but I really don't remember.
Does anyone know what's going on?
Thanks! =)

Answer 1

What is the site's URL?
It is probably caused by either of these two issues: http://blogs.msdn.com/b/ieinternals/archive/2009/12/08/aes-is-not-a-valid-cipher-for-sslv3.aspx or http://blogs.msdn.com/b/fiddler/archive/2012/03/29/https-request-hangs-.net-application-connection-on-tls-server-name-indicator-warning.aspx
The old workaround is to configure Fiddler to only use SSL3 when talking to the host in question. The newer workaround is to either use Fiddler4 with the latest .NET4.5.2 framework, or if you're using Fiddler 2.5.1, see the "SNI Hack" section of http://www.telerik.com/blogs/what-s-new-in-fiddler-4-5-1
In your OnBeforeRequest event handler, add the following code to fix the issue for certain sites:
if (oSession.HTTPMethodIs("CONNECT") && oSession.HostnameIs("BuggySite.com"))
{
oSession["https-DropSNIAlerts"] = "yup";
FiddlerApplication.Log.LogString("Legacy compat applied for request to BuggySite.com");
}

A bit late for the poster unfortunately but I just needed to add tls1.2:
Tools
Options
HTTPS
Protocols
Add tls1.2 to the end of the list and click ok

Answer 3

I was seeing the following exception:
System.Security.SecurityException Failed to negotiate HTTPS connection
with server.fiddler.network.https. HTTPS handshake to
api.etadirect.com (for #9) failed. System.IO.IOException Unable to
read data from the transport connection: An existing connection was
forcibly closed by the remote host. An existing connection was
forcibly closed by the remote host
I was able to fix it by enabling the TLS1.2 protocol which is not enabled by default for outgoing connections
Tools -> Options -> HTTPS -> click on protocols list
