SSL works on domains, so you would need to set up a domain in your local network. But why would you need SSL in LAN? ---

If not, you would have a challenge to access your DDNS from inside your local network. From external, there would be no issue to access NC using DDNS + https. However from internal, some other workarounds needed to manipulate DNS request inside your network. Depending on actual situation we could move ahead step by step to activate HTTPS, DDNS and HTTP/2 ---

to enable HTTPS/2, you would need to adjust `/etc/nginx/sites-available/default` Based on [Step-by-Step Guide: How to Enable HTTP/2 on Nginx](https://cheapsslsecurity.com/p/how-to-enable-http-2-on-nginx/) , you can add `http2` configuration within the SSL part. Should looks like this ```auto listen [::]:443 ssl http2 ipv6only=on; # managed by Certbot listen 443 ssl http2; # managed by Certbot ``` Tested on my demo system with Memories ![image](https://dietpi.com/forum/uploads/default/original/2X/c/c0fc389c8e28caff0beac806402389379e93192f.png) ---

> [@Isti6github](#): > > I added the html2 to port80 It is “http2”, about the [HTTP](https://wikipedia.org/wiki/HTTP) (transport protocol), not the [HTML](https://wikipedia.org/wiki/HTML) (website document language) 😉. And HTTP/2 is supported with HTTPS only, so adding it to port 80 at best is ignored or may break plain HTTP access. It is hence intentionally not part of the guide. I wonder why Certbot is not adding it, or whether it can be forced to do so 🤔. Oh wow, such a trivial task, requested since 2016 but not added until today: [HTTP2 support in Nginx plugin · Issue #3646 · certbot/certbot · GitHub](https://github.com/certbot/certbot/issues/3646) There is even a PR open since 2019 to add it as option, sadly it is incomplete: [Add HTTP2 Support by TheBrokenRail · Pull Request #7113 · certbot/certbot · GitHub](https://github.com/certbot/certbot/pull/7113) I think I’ll open a PR to just enable it by default. Zero reasons to not enable HTTP/2 on any webserver nowadays as of course it is backwards compatible. And of course we can do that in `dietpi-letsencrypt` until then. ---

This is a very good idea, and its can speed up some app too 😊 ---
