close Intercepting SSL Traffic on RingZer0ctf.com

If you are using Burpsuite as your proxy, you may experiment some issue regarding interception. If you got the following error unrecognized_name here is the solution.

Go to the main tab on your Burp then click on options you should now see the SSL tab. In the SSL Negociation section, check "Disable Java SNI extension (requires restart)"

Restart your Burp instance and you are good to go.
