websocket connection failed

Hello, I am following this tutorials to set up a simple Bootstrap Web-UI to communicate with a ROSbot in Gazebo: https://medium.com/husarion-blog/bootstrap-4-ros-creating-a-web-ui-for-your-robot-9a77a8e373f9

With all the required launch files launched based on this robot description: https://github.com/husarion/rosbot_description

I get the following error in the browser console:

roslib.min.js:1 WebSocket connection to 'ws://127.0.0.1:9090/' failed: Error in connection establishment: net::ERRCONNECTIONREFUSED

What am I doing wrong?
