2138	TLSv1.3 Problems	tobias992@…		"Hello,
i have problems to activate TLSv1.3. My Config seems correct - so maybe its an Bug.

nginx.conf:
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
ssl_prefer_server_ciphers on;
ssl_dhparam /etc/nginx/dh-certs/dhparam4096.pem;
ssl_ecdh_curve secp384r1;

TLSv1.3 is not working.

I installed NGINX from official docs:
