I am trying to install npm packages but it keeps giving me errors about network connectivity. I have tested by changing the registry

// 1st 
npm config set registry "https://registry.npmjs.org"
2nb
npm config set registry "http://registry.npmjs.org"

but it didn't work.

Node Version - 16.8.0

npm Version - 7.21.0

I have no idea how to solve it regardless of seeing/trying so many solutions on the internet. Please help.
