Errors yesterday when doing .sync() (possibly transient)

[slothentic]

Description

When doing .sync() yesterday, I noticed a few times that it was failing to update when attempting to fetch the package from the servers. I actually got an app rejection for it as it happened while Apple was testing and it put the app into an unhandled state.

The errors logged:

This particular instance of it the error happened on Android, I also witnessed it on iOS but was unable to capture logs unfortunately, they were roughly the same as this ^^^

Reproduction

Unfortunately this is not reproducible. I noticed it several times yesterday after not making any related changes, just noticed that it failed to update a few times, which was a condition I hadn't yet handled.

This was only observed on devices, both on iOS and Android.

[julia-fix]

Same error occured few times today while I was debugging my Android app. And when I tried 3 hours later, updates were installed with no errors. Have you found the reason?

[slothentic]

It seemed to be a transient failure. I've seen it occasionally, it looks like it may just be related to lower level networking, and not necessarily a bug.
