Please test if ping registry.npmjs.org on another computer also shows 104.18.96.96:443. And check if there is some firewall blocking the access.

Also,
I tried setting the proxy and https-proxy in the config file using npm set proxy command and tried npm install webdriverio command again and got below error:

$ npm install webdriverio
