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
Looks like this has more to do with a security improvement from Java 1.7 and server configuration than it does Charles. Can you confirm which JRM Charles is using? help -> about java
Here's an article about the same error message but after upgrading to Java 1.7:
Do you need to use Charles for those sites throwing the error? You can disable SSL Proxying per site if not.
Add -Djsse.enableSNIExtension=false to the info.plist in the Contents folder for the Charles application. In:
<key>VMOptions</key>
<string>-Xmx512m -Djsse.enableSNIExtension=false</string>
Try using command line from project's path:
mvn clean install -Djsse.enableSNIExtension=false
