Traefik Dashboard is empty

I haveve implement traefik in my production (django, postgresql, gunicorn) and all works correct when I use my /api and /admin.

But traefik's dashboard works incorrect (I can sign in and go to /dashboard/, but it shows blank fields.)

enter image description here

log:

Probably, traefik tries to make his inner api requests and can't reach them. I have api in my project with "/api/" prefix. I guess, traefik has conflict with my api. Or not?

Real host name was replaced to my.site.com.

I guess, traefik has conflict with my api. Or not?

Yes, there is a conflict.

In your example the dashboard rule is set to

- "traefik.http.routers.dashboard.rule=Host(`my.site.com`) && PathPrefix(`/dashboard`)"

However, according to the documentation on Dashboard Router Rule, you need to make sure that:

As underlined in the documentation for the api.dashboard option, the router rule defined for Traefik must match the path prefixes /api and /dashboard.

Here is the conflict with your application. Looking at the comprehensive list of Traefik's API Endpoints you could work around that by providing the following dashboard rule:

- "traefik.http.routers.dashboard.rule="Host(`my-domain.com`) && (PathPrefix(`/debug`) ||PathPrefix(`/api/http`) || PathPrefix(`/api/tcp`) || PathPrefix(`/api/udp`) || PathPrefix(`/api/entrypoints`) || PathPrefix(`/api/overview`) || PathPrefix(`/api/rawdata`) || PathPrefix(`/api/version`) || PathPrefix(`/dashboard`))"

Just make sure, that it catches all relevant endpoints and it does not interfere with your custom application.
