If you're using VPN, turn off the VPN and try again.

Firstly Check your network connection and then

npm cache clean --force

npm create react-app

The problem could easily be you are being blocked to that website by your ISP's or Company's firewall/proxy. Using the above method is quicker and easier but it's also insecure as it doesnt verify you are connected to the right website. To check if you are being blocked simply go to registry.npmjs.org in your browser. You should get some text back.

Option 1

Try this:

npm config set registry http://registry.npmjs.org/

so that npm requests for http url instead of https.

and then try the same npx create-react-app my-app command.

Option 2

You may also want to check your NPM proxy settings and perhaps remove it.

npm config get proxy
npm config rm proxy
npm config rm https-proxy
