the external url for ip-only deployment

version: '3.6'
services:
  web:
    image: 'gitlab/gitlab-ce:15.6.0-ce.0'
    restart: always
    # hostname: 'http://49.234.96.230'
    environment:
      TZ: Asia/Shanghai
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://49.234.96.230'
        gitlab_rails['lfs_enabled'] = true
        gitlab_rails['time_zone'] = 'Asia/Shanghai'
        # Add any other gitlab.rb configuration here, each on its own line
    ports:
      - '8080:80'
      - '443:443'
      - '2222:22'
    volumes:
      - '/opt/gitlab/config:/etc/gitlab'
      - '/opt/gitlab/logs:/var/log/gitlab'
      - '/opt/gitlab/data:/var/opt/gitlab'
    shm_size: '256m'

if external_url configured to http://49.234.96.230:8080, then i can't open gitlab homepage(http://49.234.96.210:8080).

but if external_url configured to http://49.234.96.230, the http url for clone is not right
