Original GitHub issue: https://github.com/asalimonov/authelia-admin/issues/37

I've been using authelia for years and have it working with Traefik, but struggling with the routing with authelia-admin.

My Authelia config is as follows, running on a dedicated subdomain

services:
    authelia:
        image: ghcr.io/authelia/authelia:4.39
        container_name: authelia
        command:
            - "authelia"
            - "--config=/deploy/configuration.server.yml"
            - "--config=/deploy/configuration.ldap.yml"
            - "--config=/deploy/configuration.acl.yml"
            - "--config=/deploy/configuration.identity.providers.yml"
            - "--config=/deploy/configuration.oidc.clients.yml"
        networks:
            - authelia
            - ldap
            - traefik
#        ports:
#            - 9091:9091
        environment:
            - TZ=${TZ}
            # Authelia Templating
            - X_AUTHELIA_CONFIG_FILTERS=${X_AUTHELIA_CONFIG_FILTERS}
            # Extras For Templating
            - DOMAIN=domain.com

        restart: unless-stopped
        labels:
            - "traefik.enable=true"
            - "traefik.docker.network=traefik"
            - "traefik.http.services.authelia.loadbalancer.server.port=${APPLICATION_PORT}"
            - "traefik.http.routers.authelia.service=authelia"
            - "traefik.http.routers.authelia.entrypoints=websecure"
            # - "traefik.http.routers.authelia.rule=Host(`authelia.domain.com`)"
            - "traefik.http.routers.authelia.rule=Host(`authelia.domain.com`) && !PathPrefix(`/auth-admin/`)"
            - "traefik.http.routers.authelia.middlewares=authelia@file, securityHeaders@file"

My authelia-admin configuration is done using environmental variables

    authelia-admin:
        image: ghcr.io/asalimonov/authelia-admin:latest
        container_name: authelia-admin

        environment:

        volumes:

        restart: no
        depends_on:
            - authelia
        healthcheck:
            test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:9093/"]
            interval: 30s
            timeout: 10s
            retries: 3
        labels:
            - "traefik.enable=true"
            - "traefik.docker.network=traefik"
            - "traefik.http.services.authelia-admin.loadbalancer.server.port=9093"
            - "traefik.http.routers.authelia-admin.service=authelia-admin"
            - "traefik.http.routers.authelia-admin.entrypoints=websecure"
            - "traefik.http.routers.authelia-admin.rule=Host(`authelia.domain.com`) && PathPrefix(`/auth-admin/`)"
            - "traefik.http.routers.authelia-admin.middlewares=authelia@file, securityHeaders@file"

If I go to authelia.domain.com I can successfully use Authelia, however trying to browse to https://authelia.domain.com/auth-admin results in a 500 error code and an internal server error.

Looking in the browser logs

Docker logs for authelia-admin are fine

dtail authelia-admin
2025-12-07T11:06:13.277836359Z Listening on http://0.0.0.0:9093

I can browse to http://SERVER_IP:9093/auth-admin and see the following page

The Authelia link points to http://SERVER_IP:9093 and the Authelia-Admin link points to http://SERVER_IP:9093/auth-admin

I understand this may be out of scope for support as it's almost certainly a Traefik issue, but I did notice that I think you're using Traefik yourself based on the compose file here

I did wonder if it might be a CORS issue, however I'm using the same Traefik routing with PathPrefix in another stack (running /.well-known/matrix/) on my root domain to facilitate OIDC in my Synapse server.

Would be very grateful for any advice, help or insights you might be able to offer.

One other thought I had, is that as you can see I've split my Authelia config file into multiple files to help with readability/editing, and I wondered if that might impact things.
