websocket connection failed

asked 2019-11-30 17:29:10 -0600

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/boot...

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

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::ERR_CONNECTION_REFUSED

What am I doing wrong?
