I've deployed Wiki, portainer and Projectsend in Docker environment app with traefik 2 as a reverse proxy. All other containers showing secure on every browser but Projectsend showing insecure on Firefox, ALl the same labels I don't why?

Here is the yaml code of projectsend,

version: "3.0"
networks:
  web:
    external: true
  internal:
    external: false
services:
  projectsend:
    restart: unless-stopped
    container_name: projectsend
    image: linuxserver/projectsend:latest
    volumes:
      - /opt/projectsend/config:/config
      - /opt/projectsend/data:/data
    environment:
      - DB_DRIVER=mysql
      - DB_HOST=db
      - DB_NAME=######
      - DB_USER=###
      - DB_PASSWORD=####
      - TABLES_PREFIX=pst_
      - SITE_LANG=English
      - MAX_FILESIZE=2048
    labels:

      - traefik.enable=true
      - traefik.docker.network=web
      - traefik.http.routers.projectsend.rule=Host(`portal.agmanagementservice.com`)
      - traefik.http.services.projectsend.loadbalancer.server.port=80
      - traefik.http.routers.projectsend.tls=true
      - traefik.http.routers.projectsend.entrypoints=websecure
      - traefik.http.routers.projectsend.tls.certresolver=lets-encrypt
    networks:
      - internal
      - web

You can check by visiting portal.agmanagementservice.com, It's showing secure on chrome and insecure on firefox,
