iOS app crashes immediately after launch with ECONNREFUSED

Please provide the following:

  1. SDK Version: 36.0.0
  2. Platforms(Android/iOS/web/all): iOS

I’ve got an ejected app which builds fine in Xcode, but as soon as it’s launched on either a simulator or a physical device, it will crash after a few seconds of the splash screen.

It seems to be related to the app trying to connect to the expo bundler and not being to.

Here is my stack trace:
