Hello self hosters! I am hoping some of you wizards can help me troubleshoot my setup with authentik and traefik.
First about my setup. I have a synology nas that is running a docker compose stack. Synology is notoriously bad at keeping their docker version fresh, but hopefully that isn’t relevant to this issue. I’m running traefik for reverse proxy, and authentik for auth. In authentik land I’ve split the outpost work into its own container, named authentikproxy. Any request to a service with the authentik-basic@file or authentik@file middleware labels applied should be routed through the authentikproxy service for auth. If it detects that one isn’t authed, it will in turn send you to the authentik frontend for SSO.
The issue is that authentik randomly stops working for random routes, or randomly fails to start working for random routes. Every time this happens I need to restart my authentikproxy and traefik containers over and over until it randomly decides to work for all my routes. When this happens I am just sent straight to the app unauthenticated. I’ll have to either input http basic credentials or use the app’s login page, whichever it has. I have found nothing in the logs after months of this going on, neither authentik nor traefik seem to be aware that anything is amiss.
I suspect the issue is to do with the docker networks but that’s honestly just a hunch.
My docker-compose file is hundreds of lines long, so I’ve stripped environment and volume info while preserving traefik labels to try to keep the info more or less concise. It is certainly still too much info but I did not want to accidentally delete something crucial. Here follows my setup.

I’ll try that, but since I haven’t been able to find any related issues I’m pretty sure it’s a configuration error on my part. Hehe the regretfully long post. Next step will probably be to open an issue on authentik’s GitHub but since I think it’s a pebkac I would prefer not to waste their time.
