You opened a grave bug and provide way less then enough information to get this solved. It might look from your perspective that you provide enough information but over here it does not. I actually get the feeling that you sit behind a RFC1149 router and *need* to make it short. WWW::Mechanize looks like something perl based but I am not going trying to figure out which package I need to install and how to use it. I asked what you are doing in order to reproduce this. The command openssl s_client -connect mbasic.facebook.com:443 negotiates TLS1.2 and openssl s_client -connect blog.cloudflare.com:443 negotiates TLS1.3. So whatever the problem is, you need to provide more informations. Sebastian
