Why ngrok suddenly started giving errors ?
npm install ngrok - failing 500 internal server error

[TaoLaMinhehe]

This error usually happens when ngrok fails to download its binary due to a server issue (HTTP 500).

You can try these fixes:

1. Clear npm cache:
   npm cache clean --force

2. Reinstall ngrok:
   npm uninstall -g ngrok
   npm install -g ngrok

3. If it still fails, try installing a specific version:
   npm install -g ngrok@latest

4. Check your network or try using a VPN (sometimes ngrok servers are blocked or unstable).

Alternatively, you can download ngrok manually from:
https://ngrok.com/download

Then add it to your PATH.

This should resolve the issue in most cases.
