Question
TLS v 1.3 Not working on Nginx

Asked by George Chanturidze
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.
I checked 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

Hello, @geochanto
May I ask if you’ve also updated the SSL ciphers as well? You should be able to enable TLS 1.3 using the following steps:
Open your Nginx server block file in /etc/nginx/conf.d/ directory or /etc/nginx/sites-enabled/ directory. Find the following line.
Add TLSv1.3 to the list of protocols.
Then add the following 3 cipher suites to your existing cipher suites.
like so:
Save and close the file. Then test Nginx configuration and reload.
Hope this helps!
