Hello,

I am trying to run Jupyter within VSCode. However, when I run it, I received the following error message:

(Error: connect ECONNREFUSED 127.0.0.1:80
at Object._errnoException (util.js:1024:11)
at _exceptionWithHostPort (util.js:1046:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1182:14))

Jupyter Notebook works fine if I run through the terminal so this is not a Jupyter installation issue.
