Panel iframe with HTTP auth

No experience with cady, but I’ll post my config with NGINX and you can see if there is any similar overlap. I’m using SWAG which runs in Docker and includes NGINX, following the guide here:

Nginx Reverse Proxy Set Up Guide – Docker

In light of the recent “hacking” stories, last week I set myself the goal of implementing Nginx. I read most related posts in this forum and elsewhere, but was unable to find a step by step guide for “enthusiasts” with limited it skills. Therefore I proceeded to do it the hard way: read, trial and error.

    cards:

        url: https://zigbee2mqtt.yourdomain.duckdns.org
        aspect_ratio: 100%
