Unhandled promise : Network request failed

Expo SDK

I’ve got this error when trying to connect to one of my api. When calling it from my browser (either on firefox on my computer or on my phone) it works and returns correctly.

[Unhandled promise rejection: TypeError: Network request failed]

Any ideas why that would happen? Is there some restrictions that would prevent Expo from connecting to the website?

Hey @davidthink,

Can you provide some more information such as what SDK version you are running, if your project is a Managed project, an ejected one using ExpoKit or a bare project? Also, is this occurring on both iOS and Android?

Cheers,
Adam

I tried on SDK 32, then upgraded it to 33 recently. It’s a pure Expo one. Cannot test on iOS right now so it’s at least happening on Android.
