title: Can't send requests from other devices to nodejs server
body: <p>I am using a React client and a node js server (MERN Stack). The server runs good on my pc but when i try to connect from my mobile phone to the ipv4 of my pc with the correct port I am unable to send requests to the server. I tried to change the proxy of the React app but it doesn't seem to work.
  Do you know what the problem might be?
  Thanks.</p>
