Can't access to Synology DSM with using subfolder (traefik without docker)

Traefik Traefik v2 (latest)
1

Hi, I'm using traefik with binary (no docker) on my server with Ubuntu 22.04 (IP 192.168.20.10). My Synology is running under IP IP 192.168.20.20 on port 5001 with self signed certificate.

I Think the problem is my missing understanding of traefik and http protocol.

This works

[http.routers.syno]
  rule = "Host(`my.domain.com`)"
  service = "syno"
  [http.routers.syno.tls]
    certResolver = "letsencrypt-resolver"

[http.services]
  [http.services.syno.loadBalancer]
    [[http.services.syno.loadBalancer.servers]]
      url = "https://192.168.20.20:5001"

This is not working if I use a path like "/syno" for access -> my.domain.com/syno.

[http.routers.syno]
  rule = "Host(`my.domain.com`)  && Path(`/syno`)"
  service = "syno"
  middlewares = ["syno"]
  [http.routers.syno.tls]
    certResolver = "letsencrypt-resolver"

[http.services]
  [http.services.syno.loadBalancer]
    [[http.services.syno.loadBalancer.servers]]
      url = "https://192.168.20.20:5001"
[http.middlewares]
  [http.middlewares.syno.stripPrefix]
    prefixes = ["/syno"]

This is the error that I receive.

How I can handle this. I want to use different services via path e.g. my.domain.com/syno, my.domain.com/service02, my.domain.com/service03 ... I have the same problem like "syno" if I try to using pihole with path.

Which part of configuration for this problem is the correct focus? Can anybody get me a hint for further investigation to handle this? :slight_smile: Thanks
