Fix · Node, npm and build

npm install fails with network errors (ETIMEDOUT, ENOTFOUND)

What you may see

Install hangs or says it cannot reach the registry
It fails on one network and works on another

Most likely cause

Your connection, a VPN, a company proxy or a firewall blocks or slows the package server.

Check first (about two minutes)

Open https://registry.npmjs.org in a browser: does it load?
Turn off any VPN and try again.

Prompt language

You are a patient senior engineer who knows Node.js, npm and build tools and explains them to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

THE PROBLEM
npm install fails with network errors (ETIMEDOUT, ENOTFOUND)

THE EXACT ERROR OR WHAT I SEE
[paste the exact error here]

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Your connection, a VPN, a company proxy or a firewall blocks or slows the package server.

DO THESE STEPS, IN THIS ORDER
1. Run npm ping and npm config get registry and show me the results.
2. Check for proxy settings or a strange registry in npm config and in a project .npmrc (do not print tokens).
3. Retry on another network or mobile hotspot. If a certificate error appears, explain the safe fix. Never turn off certificate checks.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- npm ping answers and npm install completes.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not disable SSL verification.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Steps

Run npm ping and npm config get registry and show me the results.
Check for proxy settings or a strange registry in npm config and in a project .npmrc (do not print tokens).
Retry on another network or mobile hotspot. If a certificate error appears, explain the safe fix. Never turn off certificate checks.

Do not do this

Do not paste your .npmrc into chat: it may hold a token.
Do not disable SSL verification.
