Thank you for your reply!

Personally I am fine with nginx configuration, at least when using containers. The syntax is fine and all I need to do is map one file into the container

But I took a look at the automatic cert feature and wow, that is very, very nice. I may give caddy a try for this feature only - it would simplify my current setup.

I am also surprised it allows using HTTPS over port 443 for cert renewal. I didnt even know this was possible, so I was always stuck with DNS challanges.

So again, thanks for your reply!
