My domain is: git.sdxlive.com which is dual-stacked & accessible at:

I ran this command: https://[2a01:cb00:745:c100:ba70:f4ff:fea8:f25c]/
It produced this output: Your connection is not private
My web server is (include version): nginx 1.15.8
The operating system my web server runs on is (include version): Ubuntu 19.04 disco
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): ansible 2.7.7 acme_certificate module
I have restricted on purpose the protocol to TLS 1.3 which may be an issue for https://check-your-website.server-daten.de if their system does not support that latest version.
Regarding IPv6, nginx is configured to support it for both http & https:
listen [::]:80 deferred; # redirected
listen [::]:443 ssl http2 default_server deferred;
IIUC, the certificate I received from let’s encrypt is supposed to support both IPv4 & IPv6, right?
I've created it because of the questions in this forum. To make it easier to check such configurations with different ip addresses etc. So I don't have to use a lot of different tools (dns-tools, browser etc).
