YOU, EXPO, SERVICE heavily depends on Cloud service, but has no fail-over/high-available design.
In fact, I investigate into your script, which is trivial and wasting time.

can not be connected, which seems unstable.
And there is no retrying method and other easy to recover methods to solve the environment problem.
I list my suggestions here:

1. if there is remote service unavailable, please implicitly tell the developer which service is not reachable.
2. Add more documents and notices to tell the developer, expo is not easy working in "detach" mode.
3. Provide intuitive tool to help developer organize the "detach" process.
4. Provide effective method to import native Android/iOS component into expo instead of "detach"

That's all, thank you.

Please understand a CHINSE developer's SPECIAL concern.

Hang here, why don't you give more detail about the network activity?

We rely on AWS CloudFront, which is already responsible for being highly available and having its own failover at the DNS level. If there is an issue with your network connection preventing you from connecting to one of the largest / the largest CDN on the planet, that is out of the scope of our infrastructure at the moment.

I agree we could make the error message clearer and more human-readable and have changed the title of this issue appropriately.

Please refer to the above message?
What did we get from it? Just nothing.
It's strong recommend that expo could provide more useful information

I recently took a pass at upgrading the error messages for asset uploading in #2517 if you run into any more confusing error messages please feel free to open a new issue!
