> Would fluxer resolve your auth endpoint to an IP part of a reserved local range?
Clarifying: For anyone having the same issue. If your IdP resolves to a private IP fluxer will not allow it and those codes are the one being thrown iirc.
To circumvent it try adding dns directive to your api service and set any public dns, you can also use extra_hosts to force resolving to your public IP instead. I dont think there is anyway to configure that behavior so for now I suppose having a public IP for your provider is required.
My Authentik instance is exposed to the internet via a Cloudflare tunnel. The Ubuntu Server Fluxer is running on has 1.1.1.1 and 1.0.0.1 set as the DNS servers and resolves Authentik to the public IP of the Cloudflare tunnel.
