Enable HSTS Nextcloud docker

Traefik Traefik v3 (latest)

Ok I eliminated error with these labels:

        - traefik.http.middlewares.nextcloudHeader.headers.stsSeconds=15752000
        - traefik.http.middlewares.nextcloudHeader.headers.stsIncludeSubdomains=true
        - traefik.http.middlewares.nextcloudHeader.headers.stsPreload=true
        - traefik.http.middlewares.nextcloudHeader.headers.forceSTSHeader=true
        - traefik.http.routers.nextcloud.middlewares=nextcloudHeader

Thank you! Resolved
