Cannot connect drone to gitea

Hello,

I try to install drone ans gitea on my synology NAS with docker but my configuration is not good.

I have create a docker-compose.yml:

version: "3.8"

networks:
  gitea:
    external: false

services:
  gitea:
    image: gitea/gitea:1.15.3
    container_name: gitea
    restart: unless-stopped
    ports:
      - "3000:3000"
      - "2223:22"
    environment:
      TZ: Europe/London
      RUN_MODE: prod
    volumes:
      - gitea:/data
    networks:
      - gitea
  
  drone-ci:
    image: drone/drone:2.4.0
    container_name: drone-ci
    restart: unless-stopped
    ports:
      - 89:80
      - 444:443
    depends_on:
      - gitea
    environment:
      DRONE_GITEA_SERVER: http://maria.local:3000
      DRONE_GITEA_CLIENT_ID: ******SECRET*******
      DRONE_GITEA_CLIENT_SECRET: ******SECRET*******
      DRONE_RPC_SECRET: ******SECRET*******
      DRONE_HOST: http://maria.local:89
      DRONE_SERVER_PROTO: http
      DRONE_SERVER_HOST: maria:89
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - drone:/var/lib/drone/
    networks:
      - gitea

volumes:
  gitea:
  drone:

networks:
  gitea:
    name: gitea
  drone:
    name: drone

All my container run perfectly but when i open drone page, i see network call to gitea (in debug mode) and then, i got an error :

Post "http://maria.local:3000/login/oauth/access_token": dial tcp: lookup maria.local on 127.0.0.11:53: no such host

I don’t understand this error because the IP 127.0.0.11 is not into my docker network gitea.

Any idea ?
