@wondex Could you send me the server that triggered this issue? Otherwise I won't be able to fix it. Thanks!

wondex · 2021-02-16T06:44:40Z

Hi Alban,

This is related to a Red Hat product, is there any debug option to send you the actual TlsHandshakeTypeByte value?

nabla-c0d3 · 2021-02-17T03:29:30Z

Can you show the results of a full scan against this server?

@nabla-c0d3 is the information enough? because the label "need more info" is still attached? Thanks for maintaining sslyze it's a great tool ;-)

nabla-c0d3 · 2021-02-24T03:13:40Z

@wondex To be honest I might need a live server that I can connect to, in order to be able to debug this; it looks like the server doesn't "speak" TLS. Any idea on how I could access a server that behaves like this?
