Mixed content error for self hosting

[HFulcher]

I have a self-hosted instance running on DigitalOcean behind Caddy at analytics.huwfulcher.com. Whenever I add a snippet to one of my hosted sites I get the following error

Mixed Content: The page at 'https://huwfulcher.com/' was loaded over HTTPS, but requested an insecure script 'http://analytics.huwfulcher.com:8000/js/plausible.js'.

The seemingly obvious solution would be to change to https:// but this only gives an SSL_ERROR_RX_RECORD_TOO_LONG error. I'm not sure what's going on as I have set up the docker containers according to the self-hosting instructions.

Previously if I included https:// in the BASE_URL and corresponding config for caddy-gen I could access over HTTPS but then I would get a failed to load error from Chrome/Firefox for https://analytics.huwfulcher.com:8000/js/plausible.js.

Any idea what I'm doing wrong?

What are you putting as your base URL? Can you also post your caddy config and your plausible-conf.env? Those should help shed some light on it.

Hi @Vigasaurus, find the env and caddy config below:

plausible-conf.env

ADMIN_USER_EMAIL=fulcherhuw@gmail.com
ADMIN_USER_NAME=hfulcher
ADMIN_USER_PWD=<removed>
BASE_URL=http://analytics.huwfulcher.com:8000
SECRET_KEY_BASE=<removed>

caddy config

version: "3.3"
services:
  caddy-gen:
    container_name: caddy-gen
    image: "wemakeservices/caddy-gen:latest"
    restart: always
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - caddy-certificates:/data/caddy
    ports:
      - "80:80"
      - "443:443"
    depends_on:
      - plausible

  plausible:
    labels:
      virtual.host: "http://analytics.huwfulcher.com" # change to your domain name
      virtual.port: "8000"
      virtual.tls-email: "fulcherhuw@gmail.com" # change to your email
        
volumes:
    caddy-certificates:
        driver: local

Yes I can get to the login and add sites, etc. The problem comes when an embedded snippet tries to call the api to register a pageview.

[Vigasaurus]

Hmm, yeah in that case all you should need to do is drop the port from your BASE_URL, making it https://analytics.huwfulcher.com and then stopping and starting the docker compose.

[HFulcher]

Thanks I'll give that a go, do I need to change virtual.host in caddy config to https://analytics.huwfulcher.com as well?

[Vigasaurus]

Mm, I'm not entirely sure - I don't use caddy that much - I'd assume not, but it wouldn't hurt to try if just the BASE_URL swap doesn't work.

[HFulcher]

The caddy virtual.host placeholder doesn't include http or https so I've just tried it with analytics.huwfulcher.com and that's done the trick. Thanks for your help!
