How to set up Anubis to use the same URL as the protected website(s)?

[Viable8237]

Hello,

I set up Anubis with Traefik and based on the docs I set the host to Host(`anubis.$DOMAIN`) and public URL to anubis.$DOMAIN. This works but what happens is that when accessing a website protected by the Anubis instance I get redirected to https://anubis.$DOMAIN and then back to the website so the whole flow looks like this: https://site1.$DOMAIN -> https://anubis.$DOMAIN -> https://site1.$DOMAIN.

Other websites using Anubis however do not seem to work like this and Anubis uses the same URL as the protected website instead, meaning when a user accesses https://site1.$DOMAIN, a browser first loads Anubis and then loads the website they were trying to access but all of it is happening under the same URL, there is no redirect to Anubis's own URL (e.g. https://anubis.$DOMAIN) like in my case. This also doesn't just work for one subdomain (e.g. site1.$DOMAIN) but for other subdomains as well (e.g. site2.$DOMAIN, site3.$DOMAIN etc.)

What changes should I make to my configuration so that Anubis always runs under the same (sub)domain as the website(s) it protects?

Here's a snippet of my Anubis setup:

container_name: anubis
image: ghcr.io/techarohq/anubis:main
environment:
    - BIND=:8080
    - 'TARGET= '
    - REDIRECT_DOMAINS=*.$DOMAIN
    - PUBLIC_URL=https://anubis.$DOMAIN
    - COOKIE_DOMAIN=$DOMAIN
networks:
    - traefik
labels:
    - traefik.enable=true
    - traefik.docker.network=traefik
    - traefik.http.routers.anubis.rule=Host(`anubis.$DOMAIN`)
    - traefik.http.routers.anubis.entrypoints=websecure
    - traefik.http.services.anubis.loadbalancer.server.port=8080
    - traefik.http.routers.anubis.service=anubis
    - traefik.http.routers.anubis.tls.certresolver=le

Thank you!
