407 Authentication required npm – Stack Overflow

Hello everyone I´ve been trying to configure and use npm on my enterprise PC without success.
I´ve set proxy, -proxy, strict-ssl false, registry proxy has been set like this “user:password@proxy_ip:proxy:port”
Where the password has a special character written in urlencode.
npm config get proxy
returns proxy with credentials as they should be.
I have cleared my npm cache and tried again.
No success.
Any ideas what can be the problem?

I recommend reading through this article to configure the proxy for npm.
npm config set proxy npm config set -proxy npm config set -proxy
Hope this is useful for you!

Usually, when you are behind a corporate proxy, it is needed to add the domain where you are at. Given that also the characters should be URL encoded, it would look like:
domain%5Cusername:password@proxy:port

We should add proxy with username and password to avoid this error.
For example:
username: admin
password: admin123
proxy: 172. 10. 3. 21
port: 3128
npm config set proxy admin:admin123@172. 21:3128
npm config set -proxy admin:admin123@172. 21:3128

Editing the file in user folder worked for me.
I set the proxy and npm registry as follows:
proxy=username:password@proxy:port/
-proxy=username:password@proxy:port
registry=
Note: for usenames and passwords containing special charcters, the characters need to be encoded in the proxy configuration.
e. g if username is “user” and password is “1234@user”, then the file will look like:
proxy=user:1234%40user@proxy:port/
-proxy=user:1234@user@proxy:port
where, %40 is the encoded form of “@”.
In my case, the pound symbol(#) was not getting accepted in username or password(Dont know why).

if you use windows and cntlm and you get a 407 error from cntlm proxy server, make sure that your PassNTLMv2 in the is up-to-date, as you have to recreate it, everytime that you change domain password.

Configuring a corporate proxy – JHipster

When JHipster is used in a company, you probably will need to configure all tools to bypass the corporate proxy.
You can try to configure the HTTP_PROXY and HTTPS_PROXY environment variables or use a tool like Cntlm.
But this probably won’t be enough, so you will need to configure separately all the tools that are used with JHipster.
Introduction

Supposing your proxy is defined with:
username
password
host
port
The resulting configuration is: username:[email protected]:port
If you use Cntlm, then your configuration would be: 127. 0. 1:3128. Otherwise, follow the next steps to configure each tool individually.
