I keep getting the below error when I try to simply create a new react app. I even set up fiddler on my computer and set my proxy to work with that but I am still getting the following error:
ECONNREFUSED 13.107.6.183:443

This appears to be an issue with your proxy settings since when you're running create-react-app <app_name> yarn is unable to resolve the necessary dependencies to set up your new react project, namely: react, react-dom, and react-scripts.
Maybe you could try setting your proxy settings so you can install the necessary libraries create-react-app needs. According to yarn's documentation:
"For backward compatiibilty with npm, Yarn allows passing down npm configuration via environment variables."
So maybe you could try the following and seeing if this helps resolve your issue:
npm config set proxy <proxy_url>
npm config set https-proxy <proxy_url>
where the <proxy_url> is changed to work with your appropriate proxy. Then you can tell yarn to ignore ssl if necessary. Note: Use at your own discretion.
yarn config set strict-ssl false
npm config set <key> <value> sets npm environment variables which yarn can also utilize. In this particular case we are setting the proxy environment variables. Now simply try running the create-react-app command again and it should be able to proceed with setting up the new react project for you.
Hopefully that helps!
