Hi could you try running the docker image with also these two arguments --privileged --network=host and see if you can see topics in the container?

@PrakritTyagi I ran this: "sudo docker run -it --privileged --network=host -v /Users/rohanchandra/Desktop/git/turtlebot4:/home/ubuntu/turtlebot4 --name turtlebot4_network tiryoh/ros2-desktop-vnc:humble" but it didn't work.

This is what happens when I try to run it with those arguments:
