Getting 404 not found from Traefik

I'm setting up Traefik as a reverse proxy to a bunch of docker services. Here's how I run Traefik:

services:  traefik:    image: traefik:v3.0.4    container_name: traefik    command:      # Set log level to debug      - --log.level=DEBUG      # Enable Docker provider      - --providers.docker=true      # Do not expose containers unless explicitly told so      - --providers.docker.exposedByDefault=false      # Enable File provider      - --providers.file=true      # Specify the self-signed key configuration      - --providers.file.filename=/conf/tls.yml      # Traefik will listen to incoming request on port 80 (HTTP)      - --entryPoints.web.address=:80      # Traefik will listen to incoming request on port 443 (HTTPS)      - --entryPoints.websecure.address=:443      # Redirect HTTP traffic to HTTPS      - --entrypoints.web.http.redirections.entryPoint.to=websecure      - --entrypoints.web.http.redirections.entryPoint.scheme=https      - --entrypoints.web.http.redirections.entrypoint.permanent=true    restart: unless-stopped    ports:      - 80:80      - 443:443    volumes:      - /var/run/docker.sock:/var/run/docker.sock:ro      - ./certs:/certs      - ./conf:/conf    networks:      - proxynetworks:  proxy:    name: proxy

Once Traefik is up and running, I added my first web app and I was successfully able to open the app from my browser. I then added my second and third web apps but I'm getting 404 not found on both of them. Here's how I run one of them:

services:  portainer:    image: portainer/portainer-ce:2.20.2    container_name: portainer    restart: unless-stopped    labels:      # Explicitly tell Traefik to expose this container      - traefik.enable=true      # The domain the service will respond to      - traefik.http.routers.portainer.rule=Host(`portainer.somedomain.lan`)      # Allow request only from the predefined entry point named "websecure" (HTTPS on port 443)      - traefik.http.routers.portainer.entrypoints=websecure      - traefik.http.routers.portainer.tls=true      # Specify which port Traefik should use for communicating to the service      - traefik.http.services.portainer.loadbalancer.server.port=9000    volumes:      - portainer-data:/data      - /var/run/docker.sock:/var/run/docker.sock    networks:      - proxyvolumes:  portainer-data:networks:  proxy:    name: proxy    external: true

When I perform a curl I get the following:

# HTTP$ curl -ki portainer.somedomain.lanHTTP/1.1 301 Moved PermanentlyLocation: https://portainer.somedomain.lan/Date: Wed, 31 Jul 2024 15:27:45 GMTContent-Length: 17Moved Permanently

This is to be expected because of how I set up Traefik to redirect HTTP traffic to HTTPS as moved permanently. However when I perform a curl using https:

# HTTPS$ curl -ki https://portainer.somedomain.lanHTTP/2 404 content-type: text/plain; charset=utf-8x-content-type-options: nosniffcontent-length: 19date: Wed, 31 Jul 2024 15:31:14 GMT404 page not found
