I’m currently beating my head up against Authentik. What I’m trying to do is to use Authentik to secure an unsecured service, like VS-Code server. Supposedly I can do this by pointing the domain to the Authentik server and then Authentik’s proxy points to the Code Server, but everything that I try either redirects back to Authentik or just gives me a blank screen.

Authentik and VS-Code are both running on the same system in docker, with my reverse proxy on another system.

The DNS (pihole) for both code.test and auth.test point to my reverse proxy running Caddy, and all of this is running local network only.

Any ideas what I am missing? Any help would be appreciated.


Caddyfile:

code.test.example.com {
    tls internal
    reverse_proxy auth.test.example.com
}
auth.test.example.com {
    tls internal
    reverse_proxy 192.168.1.110:9000
}

Authentik Proxy Provider:

External host: https://code.test.example.com
Internal host: http://192.168.1.110:8443
Internal host SSL Validation = false

    This looks about right, I have a similar setup for unauthenticated services here, with the difference that I’m using NGINX Proxy Manager instead of Caddy. The things I would try/check are:

    • Make sure you’ve enabled the proxy provider in the local outpost config in Authentik.
    • Declare a common network between the two containers, so that they can communicate without having to go out through the host’s IP. This way you can reference the VS Code container directly by its service name in Authentik.
    • I’m not familiar with Caddy, but I would also try changing the code.test.example.com entry to point directly to Authentik’s IP and port (in other words, both entries would look the same). In the config your posted, it seems like Caddy is redirecting through itself.
