Hello everyone,

I'm using Ubuntu Server on a Raspberry Pi 4 and SSH to run my ROS2 node. When I run ros2 node list, I can't see my node in the output. I have already tried running ros2 daemon stop and ros2 daemon start without success. When I run ros2 daemon --report, I see that the publisher and subscriber count is zero.

Here's what I have tried so far:

Restarted the ROS2 system with sudo systemctl restart ros-humble*

Note: My node is running correctly and i can see the expected output

Here are some additional details about my setup:

Operating system: Ubuntu Server(22.04.2 LTS - 64bit) on Raspberry Pi 4 ROS2 version: Humble

Can anyone suggest other steps that I can take to troubleshoot this issue? Any help would be greatly appreciated!
