Standalone Traefik mode: /api/v1/traefik-config still fetches Pangolin and returns 500 when active_data_source=traefik (middleware-manager #107)

:octopus: GitHub issue middleware-manager #107, opened by smoochy on GitHub

Summary

In my setup, Middleware Manager is configured to use standalone Traefik with active_data_source=traefik and no Pangolin present.

Codex found that GET /api/v1/traefik-config still appears to go through Pangolin fetch logic and returns 500 Internal Server Error when Pangolin is absent, even though Traefik itself is reachable and the loaded plugins are active.

This causes Traefik’s HTTP provider to stay in a retry loop and makes the Middleware Manager state misleading.

Environment

  • Middleware Manager: v4.5.0
  • Traefik: v3.6.12
  • Deployment mode: standalone Traefik
  • Active data source in config/UI: traefik
  • Pangolin: not present in my setup

I am experiencing the same issue in my environment. Could you please provide guidance on how to resolve this. I have verified that my configuration is set to active_data_source=traefik, yet the system still attempts to reach Pangolin and triggers a 500 error.
