I’m not familiar with Caddy at all - I use Traefik for a reverse proxy, and my knowledge there isn’t huge either. But I think that your reverse proxy terminates TLS (HTTPS) from the world and then forwards traffic to the appropriate service on your local network using HTTP by default - but if your local service can handle TLS, I think you can configure your reverse proxy to forward the traffic to it using TLS.

IT-Tools is kind of fun: a web page full of common tools, converters, references, cheat sheets, etc.

A few of you mentioned the “indent” - I never even saw it until I zoomed way in on the photo I took after you mentioned it. I can’t even see it in person. My vision isn’t great, but I think that suggests even more strongly a bad design.
