yarn is having troubles with the network connection

Question

I tried to install a package with yarn earlier today and I got this

yarn install
yarn install v1.9.4
[1/4]          


        

Answer 1

I have tried a lot:

• npm clean cache
• yarn clean cache
• yarn config delete proxy
• yarn config delete https-proxy
• yarn config delete registry
• yarn install --network-timeout 1000000

finally it works!
