I can't seem to get Traefik to set headers:

I have the following labels in my docker-compose.yml file:

```auto
services:
  nextcloud:
    image: 'nextcloud:latest'
    container_name: nextcloud
    build: .
    networks:
      - proxy
      - nextcloud

    volumes:
      - nextcloud:/var/www/html

    environment:
      - TZ=$TIMEZONE
      - MYSQL_HOST=$MYSQL_HOST
      - MYSQL_DATABASE=$MYSQL_DATABASE
      - MYSQL_USER=$MYSQL_USER
      - MYSQL_PASSWORD=$MYSQL_PASSWORD
      - REDIS_HOST=nextcloud_redis
      - REDIS_HOST_PASSWORD=$REDIS_PASSWORD
      - NEXTCLOUD_ADMIN_USER=$NEXTCLOUD_ADMIN_USER
      - NEXTCLOUD_ADMIN_PASSWORD=$NEXTCLOUD_ADMIN_PASSWORD
      - SMTP_HOST=$SMTP_HOST
      - SMTP_SECURE=$SMTP_SECURE
      - SMTP_PORT=$SMTP_PORT
      - SMTP_AUTHTYPE=$SMTP_AUTHTYPE
      - SMTP_NAME=$SMTP_NAME
      - SMTP_PASSWORD=$SMTP_PASSWORD
      - MAIL_FROM_ADDRESS=$MAIL_FROM_ADDRESS
      - MAIL_DOMAIN=$MAIL_DOMAIN
      - APACHE_DISABLE_REWRITE_IP=1
      - TRUSTED_PROXIES=192.168.80.0/20

    depends_on:
      - nextcloud_redis
    restart: unless-stopped

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.cloud.entrypoints=http"
  - "traefik.http.routers.cloud.rule=Host(`$HOST.$DOMAIN`)"
  - "traefik.http.middlewares.cloud-https-redirect.redirectscheme.scheme=https"
  - "traefik.http.routers.cloud.middlewares=cloud-https-redirect"
  - "traefik.http.routers.cloud-secure.entrypoints=https"
  - "traefik.http.routers.cloud-secure.rule=Host(`$HOST.$DOMAIN`)"
  - "traefik.http.routers.cloud-secure.tls=true"
  - "traefik.http.routers.cloud-secure.tls.certresolver=le"
  - "traefik.http.routers.cloud-secure.service=cloud"
  - "traefik.http.services.cloud.loadbalancer.server.port=80"
  - "traefik.docker.network=proxy"
  - "traefik.http.middlewares.cloud.headers.customFrameOptionsValue=SAMEORIGIN"
  - "traefik.http.middlewares.cloud.headers.framedeny=true"
  - "traefik.http.middlewares.cloud.headers.sslredirect=true"
  - "traefik.http.middlewares.cloud.headers.STSIncludeSubdomains=true"
  - "traefik.http.middlewares.cloud.headers.STSPreload=true"
  - "traefik.http.middlewares.cloud.headers.STSSeconds=315360000"
  - "traefik.http.middlewares.cloud.headers.forceSTSHeader=true"
  - "traefik.http.middlewares.cloud.headers.sslProxyHeaders.X-Forwarded-Proto=https"
  - "traefik.http.middlewares.cloud-dav.replacepathregex.regex=^/.well-known/ca(l|rd)dav"
  - "traefik.http.middlewares.cloud-dav.replacepathregex.replacement=/remote.php/dav/"

```

I have also verified under Traefik HTTP Middlewares that the cloud@docker is showing the following:

```auto
STS SECONDS 315360000
STS INCLUDE SUBDOMAINS True
STS PRELOAD True
FORCE STS HEADER True
FRAME DENY True

```

Yet I'm not seeing those response headers. I'm sure I'm doing something stupid but I can't figure out what.

Thanks in advance

Hi @deeztek

I only see one router with a middlewares statement.  
So the middleware is defined but not referenced.

I guess I'm confused. For example, the middleware below should be like this?

`- "traefik.http.middlewares.cloud-https-redirect.headers.STSSeconds=315360000"`

So you have defined the middleware correctly, you see it in the traefik dashboard.

The problem is no routers are using it. You likely want to add this label:

```auto
- "traefik.http.routers.cloud-secure.middlewares=cloud"

```

This line is superfluous as this is the container the route applies to.

```auto
  - "traefik.http.routers.cloud-secure.service=cloud"

```

Adding the below label as you suggested:

`- "traefik.http.routers.cloud-secure.middlewares=cloud"`

Breaks the container with the following error:

`cannot create middleware: multi-types middleware not supported, consider declaring two different pieces of middleware instead`

I'm guessing because the following label already exists:

` - "traefik.http.routers.cloud.middlewares=cloud-https-redirect"`

That is on a different router (cloud) it doesn't look like a conflict.

This sounds like there is an additional middleware type being added on a middleware definition. There might be additional context with that error that shows which one.

Were the any other changes made? What does the full labels section look like now ?

If you have two labels starting with

- traefik.http.middlewares.name.addprefix
- traefik.http.middlewares.name.basicauth

where `addprefix` and `basicauth` are some arbitrary middlewares, and the `name` is the same middleware (instance) name you will get the error you are seeing. make sure that you do not have anything like that (even across different containers)
