GitHub Actions workflow error: Run Command Timeout! Even if the script did well

问题

I want to deploy my Nuxt.js application on my remote server each time I commit into repository. Here is my deploy.yml:

name: 'Deployment'

on:
  push:
    branches: ['master']

jobs:
  deploy:
    name: Deploy
    runs-on: ubuntu-latest
    steps:
    - name: Connect to SSH
      uses: appleboy/ssh-action@master
      with:
        host: webhostgb.com
        username: root
        key: ${{ secrets.PRIVATE_KEY }}
        port: 22
        script: |
          cd whgb-new
          git pull origin master
          npm run build
          fuser -kn tcp 3000
          pm2 restart deploy.sh

Basically deploy.sh runs npm start, but I use pm2 to create another process instead of doing the deployment in GitHub actions process

And I after 10 minutes I get this error, even if it did well:
