Azure-functions-core-tools: Error: self signed certificate in certificate chain

[Kaushik27]

When ever I am trying to execute the following command:
npm install -g azure-functions-core-tools@3 --force,
I am getting the following error:
attempting to GET "https://functionscdn.azureedge.net/public/3.0.2534/Azure.Functions.Cli.win-x64.3.0.2534.zip"
using proxy server "http://*:*@*.**.com"
Error: self signed certificate in certificate chain

Furthermore,
I have already tried many available option suggested by node community like

• npm config set NODE_TLS_REJECT_UNAUTHORIZED=0
• npm config set strict-ssl false --global
• npm config set registry http://registry.npmjs.org/
• npm config set ca=""
• npm install npm -g --ca=null

While its working for some folks but for many its still an open issue.
Please look into this, this had become a show stopper in Function App Design.

@Kaushik27 Can you try downloading the file from your browser? Does it give a similar error?

[Kaushik27]

@anthonychu, yeap I am able to download the zip file directly from the browser.
Its just not working when package manager tries to install it.
Let me know if you need anything else.
