Help with Setting up proxy

Thanks for the tutorial. But I need one help, for internet I am using my company proxy, and when I changed it to 127.0.0.1:8080, then my internet is not working, could you please facilitate me. Thanks

One will want to verify their local proxy is setup to forward traffic to the company proxy. IE upstream proxy configuration.
