Always getting page not found even for dashboard

Traefik Traefik v3 (latest)
1

I can not understand why I am getting the error: "404 page not found"
all the time (including dashboard). My redcap-admin exposes port 8080 yet i can not get anything. Through Traefik it is needed to pass request coming from 443 to the redcap-admin container using its 8080 port. From within the redcap-admin container I get response using

wget redcap-admin:8080

I get content but if using

https://${RC_SAML_HOSTNAME}/manage

I get 404 page not found

Any suggestions, please?

More information:

/etc/traefik/traefik.yml is:

What do you get for

wget redcap-admin:8080/manage

You have tls as Traefik static config root element, that does not work, it belongs in a dynamic config file, loaded via providers.file.

You set .tls=false but access the entrypoint and router with https, which should not work.

Custom TLS certs need to be loaded and then enabled on an entrypoint or router.

wget redcap-admin:8080/manage I get an html file quite different to the 404 error page.

I created a new topic incorporating your ideas at:

Yet, I still have problems.

Thanks

For traefik: I changed the labels section to:

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.mydashboard.rule=Host(`${RC_TRAEFIK_HOSTNAME}`)"      
      - "traefik.http.routers.mydashboard.entryPoints=web443"
      - "traefik.http.routers.mydashboard.service=api@internal"
      - "traefik.http.routers.mydashboard.middlewares=auth"  
      # - "traefik.http.services.traefik.loadbalancer.server.scheme=https"
      # - "traefik.http.services.traefik.loadbalancer.server.port=443"
      - "traefik.http.middlewares.auth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/,test2:$$apr1$$d9hr9HBB$$4HxwgUir3HP4EsggP/QNo0"

and the ports: section to:

    ports:       
       - "443:443"

and now I can see the login page. Still, I could not answer my question on how to use port 8443 instead of 443 for Traefik.

To just change the external port number, you can use:

    ports:       
       - "8443:443"
