TLS 1.3 not being selected.

June 03, 2018 12:33AM
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:

testssl.sh does report TLS 1.3:
