The problem is that the rosbridge server was not running. Before you can use the rosbridge address, you need to start the rosbridge server as indicated in the first unit. Run on a separate web shell:

roslaunch course_web_dev_ros course.launch

Then try connecting again.

We’ll update the course to make this clearer.
