iOS 14: network retry when prompting for local network access

[hexsprite]

iOS 14 has introduced a dialog to ask users if they will permit an app to access the local network. This appears for the first time when a Cordova app attempts to do a hot code reload if testing on the local network. It should be fixed so that it retries the request in this situation. Currently it fails and the app remains in the older version until the app is restarted/reloaded.

How to reproduce:

• run ios-device sample (I used clocks demo, updated to latest)
• make a change in any template to trigger HCP

@hexsprite what is this repo clocks demo?

I never saw this problem before. In which cases it would happen? On real devices in the first HCP?

If that is really the case, I'm not getting this problem on my apps, what would be the workaround in your opinion?

[hexsprite]

Probably be more persistent at retrying failed requests for HCP would fix it.

Yeah its just the clocks demo, wanted something neutral to reproduce with.
