I am using Charles 3.7 to debug SSL connections. I was able to view most of the HTTPS connections, however there is 1 or 2 sites that returned "SSLProtocol: handshake alert: unrecognized_name" when I try to debug it, and I was unable to load the website with Charles on. I am able to do so using Fiddler. Any ideas on how to resolve this issue? Thanks.

I came across this when using the latest beta Charles 3.10b9 on 10.10. We fixed by using a similar method to Shade's answer:
I opened info.plist in Xcode and did the following:
Under the JVMOptions (as oppose to VMOptions) key add the string:
-Djsse.enableSNIExtension=false
