Npm install : FetchError: request to http://registry.npmjs.org/... failed, reason: read ECONNRESET - npm

Question

Trying to install any node package using npm hangs for about 5 mins then gives a ECONNRESET network error. I have been using npm for other projects recently and it worked fine but now will not work for any project(Including clean npm init)
npm i ws
This is on a Raspberry pi 3 running on my home network with no proxy requirements. All other machines both linux and windows are working fine.
npm -v = 6.4.1
I have tried the following:
npm i ws This gives me the ECONNRESET error (See below)
Curl https://registry.npmjs.org/
& Curl https://registry.npmjs.org/ws
Both return the correct json response
Removing any proxy settings
npm config rm proxy
npm config rm https-proxy
npm config set registry http://registry.npmjs.org/
Restarting etc
Full Error log:
npm i ws --save --verbose
npm info it worked if it ends with ok

Answer 1

First check following thing:
ping registry.npmjs.org
You will get to know the IP address from that like below:
PING registry.npmjs.org (104.16.20.35) 56(84) bytes of data.
Then
sudo vi /etc/hosts
104.16.20.35 registry.npmjs.org
Then try to do following
npm install
