Description of the bug

No demo scenario can be launched properly

More precisely, the fleet adapter cannot connect to the server

[fleet_adapter-15] [ERROR] [1718262000.911974934] [tinyRobot_fleet_adapter]: Connection lost
[fleet_adapter-15] > Reconnecting in 1s
[fleet_adapter-15] > Host: ws://localhost:8000/_internal
[fleet_adapter-15] [INFO] [1718262001.912357421] [tinyRobot_fleet_adapter]: Attempting to connect to ws://localhost:8000/_internal
[fleet_adapter-15] [ERROR] [1718262001.913277417] [tinyRobot_fleet_adapter]: Connection to ws://localhost:8000/_internal failed. Reason:

[fleet_adapter-15] > Status: Closed
[fleet_adapter-15] > Remote Server: None Specified
[fleet_adapter-15] > Error/close reason: Underlying Transport Error
[fleet_adapter-15] 

This causes the scenarios to not be usable as is.

Steps to reproduce the bug

Follow the instructions here

docker pull ghcr.io/open-rmf/rmf/rmf_demos:latest
docker tag ghcr.io/open-rmf/rmf/rmf_demos:latest rmf:latest
docker run -it --network host rmf:latest bash -c "export ROS_DOMAIN_ID=9; ros2 launch rmf_demos_gz office.launch.xml headless:=1"

Expected behavior

Launch with no problem nor tinkering needed

Actual behavior

Cannot use as is

Additional information or screenshots

This problem occurred since yesterday ( 12 June ) and maybe before when I tried to run some demos to try new things but failed, Today I tried launching from docker but failed too.

Start with the Docker container instructions and the ros2 launch rmf_demos_gz office.launch.xml headless:=1 command on Ubuntu 22.04. Reproduce the fleet adapter's failed connection to ws://localhost:8000/_internal; done means the official image launches the demo scenario without tinkering.
