Error on connection registry.npmjs.org via npm update

Hi guys, if you get an error like below on npm update. You can set npm strict-ssl false on terminal by typing 

npm config set strict-ssl false

Hostname/IP does not match certificate's altnames: Host: registry.npmjs.org. is not in the cert's altnames: DNS:a.sni.fastly.net, DNS:a.sni.global-ssl.fastly.net

If problem didn't solved you can try set dns 8.8.8.8 at your /etc/resolv.conf for linux.
