harbor installation: network between harbor dockers is not connected

[HowHsu]

Follow the official doc to install Harbor, but the network between docker instances seems not connected.
the detail install process is: wget the v2.10.2 tgz installer, then extract it, then comment the https part in harbor.yml, then sudo ./install.sh.
docker version: 26.1.3
docker-compose version: v2.27.0

output of sudo docker-compose ps

Please check your docker network settings, please do not use the 192.168.x.x for docker container network, it is easy to overlap with the host network, please refer https://serverfault.com/questions/916941/configuring-docker-to-not-use-the-172-17-0-0-range

Solved by reboot the server, it should be some issues with network policies not active.
