I have Ubuntu 18.04, Nginx version 1.17.6, OpenSSL version 1.1.1 . - I believe those satisfy requirements for TLS 1.3.
In my /etc/nginx/nginx.conf file I added TLSv1.3 like so:
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
I have not changed anything in **/etc/nginx/sites-available/website.com **.
When I test my site in SSL Labs and elsewhere, TLSv1.3 is not working.
nginx -V, and --with-openSSL argument is not listed. Not sure if I have to rebuild my nginx with that flag.
Any pointers would be appreciated
