First, thank you in advance for taking a look. I think I have a very basic mistake somewhere, but I have searched for hours with no result. I am trying to run a proof of concept to expose a container behind a traefik 2.4 reverse proxy at a subdirectory. My DDNS does not allow for subdomains, so I am stuck with subdirectories until I can prove this works. My problem is every container I stand up is dynamically picked up by traefik and shows up in the dashboard, but the subdirectory gives a 404 error. I have even used PathPrefix with a regex to prevent the ending / error. Here is my configuration. Traefik's docker-compose: ```auto version: '3' services: traefik: image: traefik:v2.4 container_name: traefik restart: unless-stopped security_opt: - no-new-privileges:true networks: - t2_proxy ports: - 80:80 - 443:443 volumes: - /etc/localtime:/etc/localtime:ro - /var/run/docker.sock:/var/run/docker.sock:ro - ./data/traefik.yml:/traefik.yml:ro - ./data/acme.json:/acme.json - ./data/log:/var/log labels: - "traefik.enable=true" - "traefik.http.routers.traefik.entrypoints=http" - "traefik.http.routers.traefik.rule=Host(`domain.host.com`)" - "traefik.http.middlewares.traefik-auth.basicauth.users=user:password" - "traefik.http.middlewares.traefik-https-redirect.redirectscheme.scheme=https" - "traefik.http.routers.traefik.middlewares=traefik-https-redirect" - "traefik.http.routers.traefik-secure.entrypoints=https" - "traefik.http.routers.traefik-secure.rule=Host(`domain.host.com`)" - "traefik.http.routers.traefik-secure.middlewares=traefik-auth" - "traefik.http.routers.traefik-secure.tls=true" - "traefik.http.routers.traefik-secure.tls.certresolver=http" - "traefik.http.routers.traefik-secure.service=api@internal" fail2ban: image: crazymax/fail2ban:latest container_name: fail2ban network_mode: "host" cap_add: - NET_ADMIN - NET_RAW volumes: # - /var/log:/var/log:ro - ./fail2ban/data:/data - ./data/log:/var/log:ro networks: t2_proxy: external: true ``` Here is my traefik.yml configuration file: ```auto api: dashboard: true entryPoints: http: address: ":80" https: address: ":443" providers: docker: endpoint: "unix:///var/run/docker.sock" exposedByDefault: false certificatesResolvers: http: acme: email: email@email.com storage: acme.json httpChallenge: entrypoint: http log: filePath: "/var/log/traefik.log" level: DEBUG accessLog: filePath: "var/log/access.log" filters: statusCodes: - "400-499" retryAttempts: true ``` Here is the first proof-of-concept container I'm trying to expose. It's just portainer in a separate docker-compose: ```auto version: '3' services: portainer: image: portainer/portainer-ce:latest container_name: portainer restart: unless-stopped security_opt: - no-new-privileges:true networks: - t2_proxy ports: - "9000:9000" volumes: - /etc/localtime:/etc/localtime:ro - /var/run/docker.sock:/var/run/docker.sock:ro - ./data:/data labels: - "traefik.enable=true" #web routers - "traefik.http.routers.portainer.entrypoints=http" - "traefik.http.routers.portainer.rule=Host(`domain.host.com`) && PathPrefix(`/portainer`)" #- "traefik.http.routers.portainer.rule=Host(`domain.host.com`) && PathPrefix(`/portainer{regex:$|/.*}`)" #- "traefik.http.routers.portainer.rule=Path(`/portainer`)" #- "traefik.http.routers.portainer.rule=PathPrefix(`/portainer{regex:$|/.*}`)" #middlewares #- "traefik.http.routers.portainer.middlewares=portainer-stripprefix" #- "traefik.http.middlewares.portainer-stripprefix.stripprefix.prefixes=/portainer" - "traefik.http.middlewares.portainer-https-redirect.redirectscheme.scheme=https" - "traefik.http.routers.portainer.middlewares=portainer-https-redirect" #web secure rpiters - "traefik.http.routers.portainer-secure.entrypoints=https" - "traefik.http.routers.portainer-secure.rule=Host(`domain.host.com`) && PathPrefix(`/portainer`)" #- "traefik.http.routers.portainer-secure.rule=Host(`domain.host.com`) && PathPrefix(`/portainer{regex:$|/.*}`)" #- "traefik.http.routers.portainer-secure.rule=Path(`/portainer`)" #- "traefik.http.routers.portainer-secure.rule=PathPrefix(`/portainer{regex:$|/.*}`)" #- "traefik.http.routers.portainer-secure.middlewares=chain-basic-auth@users" - "traefik.http.routers.portainer-secure.tls=true" - "traefik.http.routers.portainer-secure.tls.certresolver=http" - "traefik.http.routers.portainer-secure.service=portainer" - "traefik.http.services.portainer.loadbalancer.server.port=9000" - "traefik.docker.network=t2_proxy" networks: t2_proxy: external: true ``` Please let me know if I should post any other details. I sense I am missing a very obvious bit of configuration, as this is my first time using Traefik. Thanks again for any help! ---

Hello @transistor, Thanks for your interest in Traefik! As the forwarded request contains the `/portainer` path a `404 Not Found` error is returned by Portainer because it does not exist. To remove the `/portainer` path from the forwarded request you can use the [strip prefix middleware](https://doc.traefik.io/traefik/middlewares/stripprefix/). The following labels have to be added to the portainer container: ```auto - "traefik.http.routers.portainer-secure.middlewares=portainer-stripprefix" - "traefik.http.middlewares.portainer-stripprefix.stripprefix.prefixes=/portainer" ``` With those labels, the `404` error is fixed but the portainer UI is not loading properly. That's because the UI requests don't contain the portainer path (which is required to match the `router` rule). It seems that it's currently not possible to configure portainer to add this prefix: [[FEAT] Add path prefix to web UI · Issue #3901 · portainer/portainer · GitHub](https://github.com/portainer/portainer/issues/3901) IMO the only solution is to use a dedicated domain in the `router` rule. ---
