Describe the bug

Netlify CLI consistently crashes with Error: read ECONNRESET when attempting to proxy to a Nuxt 4.x development server on Node.js 24.6.0. The crash occurs immediately after the Nuxt dev server successfully starts and builds. The error is unhandled and terminates the Netlify CLI process.

Error Output:

Error: Netlify CLI has terminated unexpectedly
Error: read ECONNRESET
    at TCP.onStreamRead (node:internal/stream_base_commons:216:20)

This appears to be a socket handling incompatibility between Netlify CLI and Node.js 24.x.

Steps to reproduce

1. Install Node.js 24.6.0
2. Create a fresh Nuxt 4.x project

npx nuxi@latest init test-project --packageManager npm --no-gitInit
cd test-project`
3. Create netlify.toml:
`[dev]
  framework = "nuxt"
  port = 8888
  targetPort = 3000
  autoLaunch = false

4. Run Netlify Dev
5. Wait for it to complete then load localhost:8888

Configuration

netlify.toml:

[dev]
  framework = "nuxt"
  port = 8888
  targetPort = 3000
  autoLaunch = false

package.json:

{
  "name": "nuxt-app",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "dependencies": {
    "nuxt": "^4.2.0",
    "vue": "latest"
  }
}

nuxt.config.ts:

export default defineNuxtConfig({
  compatibilityDate: '2024-11-01',
  devtools: { enabled: true }
})
