OIDC app not working without Proxy provider app

[hansolo57]

Hi everyone,

I have a question about the configuration of applications when they use OIDC providers. I use docker and Traefik to run several applications as Apache Guacamole, Traefik or WikiJs on the same host.

I created an OIDC provider and an app who use the provider to authenticate on Apache Guacamole. It doesn't work. Once I am authenticated on Authentik, I can't be redirect to Guacamole. And the same problem if I go directly to Guacamole.

In Authentik, if I create a proxy provider and an app who use the proxy provider to go to Guacamole, without delete the OIDC app/provider, it works fine. I mean the OIDC works fine in this case.

If I delete the proxy app/provider to Guacamole, the OIDC authentication doesn't work anymore. I have Client Id Error (client_id is missing or invalid).

I have this problem for WikiJs and Guacamole. What's going wrong ? Is is an outpost or docker problem ?

Thanks
