I recently set up a site with
certbot --nginx -d <domain>. In
/etc/letsencrypt/options-ssl-nginx.conf, I added TLSv1.3 to the
ssl_protocols directive. However, when I visit the site (Chrome 68), the security tab shows TLSv1.2. I tested the site with ssllabs.com, which also showed only TLS versions 1.0-1.2 enabled.
I don't see any errors in
journalctl -u nginx.service | grep -i tls or
grep -i tls /var/log/nginx/*.log.
How could I troubleshoot this issue? I've checked all my config files and all my log files and haven't found the source of (or any information about) the problem.
- certbot 0.23.0
- nginx version: nginx/1.14.0 (Ubuntu)
- OpenSSL 1.1.0g 2 Nov 2017
- Ubuntu 18.04
- Linux 4.15.0-20-generic x86_64
