reactjs - Can't load expo app: Something went wrong

Question

I've created an expo app with exp init MyApp command and started it by running exp start in MyApp directory.

Then I'm scanning barcode which was printed in console with expo mobile app on android device.

Then "Something went wrong" screen is rendered instead of the app.

View log shows "Uncaught Error: Couldn't load exp://.....".

No errors in expo packager console output.

It used to work sometimes ago.

For me the problem was happening when running over WiFi, as the tools always use the your first connection (you can check it by running ipconfig) and my first connection was internet.

If that's you case you may try this workaround for changing you connections priority:

1. Go to Control Panel > Network and Internet > Network Connections
2. Right click the desired connection (Higher Priority Connection)
3. Click Properties > Internet Protocol Version 4
4. Click Properties > Advanced
5. Uncheck 'Automatic Metric'
6. Enter 10 in 'Interface Metric'
7. Click OK
