Use my own certificates for docker containers, but get -404 page not found- error

Traefik Traefik v2
1

Hi all!

I'm completely new to Traefik. I want to reach the docker containers via https with my own wildcard-certificate, unfortunately without success. As template I used the following config-files (based on letsencrypt) as these are very close to what I want to achieve:

As soon as I open the following url's via browser, I get a blank page with '404 page not found' error:

https://traefik.vm-ubuntu-docker/
https://portainer.vm-ubuntu-docker/

The certificate is at least loaded each time.

All containers are in the same network, which I created by 'docker network create proxy'.

At the time I start the containers (docker-compose up) and at the time I try to open the url's I get no log-output besides:

time="2021-11-17T00:23:52+01:00" level=info msg="Configuration loaded from file: /traefik.yml"

I have now spent a few hours with it and have played through a number of variants but always without success, here is my final adapted configuration:

docker-compose.yml

Can someone help me to find the error or the cause? I'm really desperate.

Can nobody help me with that issue? I checked more than once and tried variants of the configs but always with same result. Currently I have a working environment but with nginx/npm, so containers are healthy in this regard. I will not give up upon traefik yet, because I want to in the next step setup a ssl-passthrough routing for a container and as I understood is nginx not a good choice for that. So please, who can help?
