As you can see from the log, Node-RED needs to be able to download modules from `https://registry.npmjs.org` - this is typical of any node based application that pulls from NPM.

There are some (not many) nodes that also pull from `github` - you may wish to include that too.

And you might want to think about DNS and retrieving time settings also as firewall exceptions
