public npm registry not accessible after upgrade to HANA 2.0 sp3

Hi,

After upgrading to HANA 2.0 sp3 I am unable to access the npm registry.

My UPSTREAM_LINK env is set to http://registry.npmjs.org/ (same as in SP 2) and no HTTP_PROXY env is set because it is not required in the server. (I am able to access npmjs.org through curl without any proxy setting).

The error I received is

http  --> ERR, req: 'GET http://registry.npmjs.org/ws', error: unable to get local issuer certificate (connecting to registry.npmjs.org:443)

All the settings were same as in sp2.

Any help is appreciated.
