Uncaught Error: Packager is not running at http://192.168.0.100.19001

Question

I ran an app in a normal way in React-Native (EXPO):

• expo init Myproject
• cd Myproject
• start of wire

However, next to running the app, the following message appears:

_ Something went wrong. (I.e. _ ** The marshaler is not running at http: //192.168.100.19001**_

What do I do?

Answer 1

I found that this error message could arise for a very simple reason, make sure your smartphone running Expo is connected to the same subnetwork as your computer on which your dev server is running.

Answer 2

After 5 hours of serious debugging, this article helped me. Packager is not running at expo.

Restart all the devices.

That includes: Your computer, phone, router.

Answer 3

To resolve this issue of Packager is not running at http://192.168.0.100.19001 ensure the computer and phone are on the same network.

Answer 4

I faced same issue and tried so many refresh and resstart. and I observed my pc had switched networks and was on a different network. Switching to be on the same network as my phone resolved the issue.
