External services behind Traefik?

I have Traefik 2 up and running on a server with a bunch of my other docker services. I have a separate synology NAS and another laptop I want to install nextcloud on. I've added a file to the rules folder to access the nas but it's not working.

Here is my nas.yml

http:
  routers:
    nas-rtr:
      rule: "HostHeader(`nas.example.me`)" 
      entryPoints:
        - https
      middlewares:
        - chain-no-auth
      service: nas-svc
      tls:
        certResolver: dns-cloudflare
  services:
    nas-svc:
      loadBalancer:
        servers:
          - url: "http://192.168.10.123:788"

This is my middleware chain for no auth contains the rate limit and secure-headers middleware. Here they are

http:
  middlewares:
    middlewares-rate-limit:
      rateLimit:
        average: 100
        burst: 50

    middlewares-secure-headers:
      headers:
        accessControlAllowMethods:
          - GET
          - OPTIONS
          - PUT
        accessControlMaxAge: 100
        hostsProxyHeaders:
          - "X-Forwarded-Host"
        sslRedirect: true
        stsSeconds: 63072000
        stsIncludeSubdomains: true
        stsPreload: true
        forceSTSHeader: true
        # frameDeny: true #overwritten by customFrameOptionsValue
        customFrameOptionsValue: "allow-from https:example.me" #CSP takes care of this but may be needed for organizr.
        contentTypeNosniff: true
        browserXssFilter: true
        # sslForceHost: true # add sslHost to all of the services
        # sslHost: "example.me"
        referrerPolicy: "same-origin"
        # Setting contentSecurityPolicy is more secure but it can break things. Proper auth will reduce the risk.
        # the below line also breaks some apps due to 'none' - sonarr, radarr, etc.
        # contentSecurityPolicy: "frame-ancestors '*.example.me:*';object-src 'none';script-src 'none';"
        featurePolicy: "camera 'none'; geolocation 'none'; microphone 'none'; payment 'none'; usb 'none'; vr 'none';"
        customResponseHeaders:
          X-Robots-Tag: "none,noarchive,nosnippet,notranslate,noimageindex,"
          server: ""

Any help would be greatly appreciated.
