React project for Neutrinojs displays “Invalid Host/origin Header” in console

Question

When I create a Neutrinojs v.9 project

Davids-iMac-Pro:repos davidedelhart$ create-project test-n9

... Welcome to Neutrino! 👋 To help you create your new project, I am going to ask you a few questions.

? 🤔  First up, what would you like to create? A web or Node.js application
? 🤔  Next, what kind of application would you like to create? React
? 🤔  Would you like to add a test runner to your project? Jest
? 🤔  Would you like to add linting to your project? Airbnb style rules

👌  Looks like I have all the info I need. Give me a moment while I create your project!

   create test-n9/package.json
   create test-n9/.neutrinorc.js
   create test-n9/webpack.config.js
   create test-n9/src/App.css
   create test-n9/src/App.jsx
   create test-n9/src/index.jsx
   create test-n9/jest.config.js
   create test-n9/test/simple_test.js
   create test-n9/.eslintrc.js

...

Now change your directory to the following to get started:
  cd test-n9

❤️  Neutrino
Davids-iMac-Pro:repos davidedelhart$ cd test-n9/
Davids-iMac-Pro:test-n9 davidedelhart$ yarn 
yarn install v1.12.3

I get repeated "Host/Origin header" disconnected message:

What is this coming from, and what does it take to make it go away?

Thanks

This same error comes in angular also. I know how to handle in angular but I don't know in react. Still I have do some RND on that and I got this.

HOST into .env file

HOST=server.com

Then restart the development server.
