Not able to run detox test (Error: connect ECONNREFUSED)

[jln-dk]

Description

I followed the "Getting Started" guide carefully step by step, on a completely new React Native project (react-native init).
Running detox build works fine, but detox test does not. It results in this error:

I am not behind any specific/corporate proxy, and I have never met NPM connection errors like that before.

Steps to Reproduce

1. Followed the "Getting Started" docs
2. Install all the latest dependencies as of this date today
3. Init a new React Native project
4. Run detox build and then detox test

Something is blocking connection. Perhaps you have a firewall application that is preventing the server port opening.
