I'm setting this right now even when running 3.1 built with golang 1.15. From what I can tell there are issues with 1.3 negotiation with certain servers. I'm still trying to get to the bottom of it.

@IPv4v6 can you please share the local configuration that you have that builds binaries that works against tls13.1d.pw ?

Thank you!

Hi all,

We went through the rabbit hole of figuring out what was wrong, turns out that the server had an issue. For more information see here:

Thanks!

I also saw that error (tls: error decoding message) when testing with my self-compiled gobuster binary at the time the server was broken.

To make it clear: the current gobuster Kali package binary has a problem.
