Hi,
I just connected to the real robot for ROS2 Navigation course. However, I could not do anything. I tried to launch the rosbridge and it crashed. The commands that I launched are the ones given in the jupyter notebook.
I got the following prompts when running rosbridge:

I would appreciate if you give me feedback on what could be the reason for this, I have just spend 50 min of real robot session without testing my main code.
Kind regards,
