Hi,
I can't see what I'm doing wrong.
When I visit https://www.cloudflare.com/ with my browser TLS 1.3 is used.
However when I visit my website, TLS 1.2 is selected instead.
My browser (opera 53) has this in its command line: " --ssl-version-max=tls1.3 --tls13-variant=draft"
Nginx is compiled like this:
nginx version: nginx/1.14.0
built with OpenSSL 1.1.1-pre7 (beta) 29 May 2018
