Docker compose with Traefik results in 404 - docker

We are trying to configure api and frontend with docker-compose using Traefik and we need that both applications are exposed by domain.
With this configuration we get 404 but commented "frontend" lines make api works.
In Traefik dashboard we can see both applications in "HTTP Services" tab as loadbalancer but we have no routers in "Routers" tab.
What we miss?
We also tried using "network" with no luck (receive "gateway time out").

I want docker to listen to "http://localhost/user" and forward to "http://portal.local/user" using traefik

I've got my docker environment setup using traefik and I've got two services running at the moment.
I'm using Google OAuth for authentication which redirects to my web application with auth-code. The redirect URL isn't allowed anything but localhost or localhost:<any-port> or any CDN. I've setup my docker for http://portal.local.
I now want http://localhost/user/googleLogin?code=xxxxxxxxxx to be translated to http://portal.local/user/googleLogin?code=xxxxxxxx for further processing of authentication.
Right now, I'm having to manually change localhost to portal.local in browser URL after it gives site not found error, which then takes me to further processing.
Below is my docker-compose.yml file.

I've tried to use multiple router rules to listen to both localhost and portal.local using regex/replacement middlewares as well but that stops the service at all and gives 404 error.

Multi Docker-Compose projects sharing service

I am attempting to create multiple Docker-Compose projects and have them share a single service, a database server. I'm currently unable to get projects to use my mariadb instance. I'm not sure if my issues is in traefik or docker. I can get wordpress to recognize the database if it is included in the same docker-compose, but as I would ultimately like to not have multiple instances of a database server running, I would prefer it to be it's own project.

You can have multiple docker-compose files, with the same network and run them together as below:
docker-compose -f docker-compose-1.yml -f docker-compose-2.yml up -d
But if you need the services to recognize eachother, the networks should be the same. Give your traefik_t2_proxy network to mysql too.

Proxy web interface with help traefik

I'm trying to proxy the pgAdmin web interface using segment URLs. But I have some problems with this.
When I'm accessing the browser with the following URL -> http://localhost/pgadmin, it redirects me to the following URL -> http://localhost/login?next=%2F. This is the internal routing of pgAdmin.
I want routing to be next http://localhost/pgadmin/login?next=%2F.
Could you tell me how can I achieve this.
Here is an example of my docker-compose configuration
