Hello,

I am getting the following error in fiddler and without Capture HTTPS CONNECTs it works, also in the Protocols I have enabled: <client>;ssl2;ssl3;tls1.0;tls1.1;tls1.2

You should remove both SSL2 and SSL3 from your supported protocols list, as SSL3 is not secure (and generally not used any more) and enabling SSL2 will break modern TLS versions.

Telerk should probably remove mention of SSL2 from the UI and may want to show an explicit warning if a user manually adds it.
