TLS Problems

Ivan Nicola Biagi Dec 30, 2019 04:22AM UTC

I get on 90% hosts the ssl error for handshake: Received fatal alert: hanshake_failure.
I'm using burp with embedded JRE and SNI extensions disabled.
I've also tried to remove TLS 1.3 in list because the host maybe doesn't support it but no luck.
I have latest version of Burp Suite Professional 2.1.07, any advice?
Is this a bug?
Let me know because I need to proceed with my testings and my work at the moment is blocked.

Ivan, is the site you are working on publicly accessible? If so, could you email the details to

Alternatively, could you provide screenshots of the error messages?

Hi, actually during test i've seen that with java 8 the problem doesn't appear. Any ideas why?
I also suggest to use BouncyCastle library as they have much more support for SSL and minor problems.

Glad to hear you resolved your issue by using a different Java version.

In version 2.1.07, we have improved our SSL/TLS coverage ( This was done by using the BouncyCastle library.

Yeah, but no luck for other hosts!
That's strange by the way, because with owasp zap i have no problem connecting.
Maybe i've setupped something bad?
Any ideas? Except for SNI disabled and accept invalid SSL certificates (in project options->tls).

Maybe this could be a problem of website's certificate?

Thanks for support!
