I have already tried

1. set registry to http://registry.npmjs.org/
2. set strict ssl to false

Answer 1

1) Did you check your internet settings to check whether the proxy settings are enabled?

2) Did you check environment variables for HTTP_PROXY, HTTPS_PROXY? If those values are set, remove them and problem will be solved.
