PhoneGap application under Anrdoid stopped sending Ajax requests - what could be the reason?

Question

JavaScript

Quite recently, the PhoneGap application under Anrdoid stopped working, the interface of which was built on the basis of: Framework7 (version 1.4.2 ). The same application for iOS works flawlessly.

Naturally, the first thing I did was debugging according to the instructions: docs.phonegap.com/references/developer-app/debugging

Debugging did not give me anything in terms of any JavaScript errors:

However, it became clear that the application cannot send Ajax requests :

or rather, they seem to hang in the status: Pending

On the server where requests fly, I set a trap: requests do not reach there ...

What should I do? Where to dig? With what it can be connected? What to pay attention to?

Answer 1

The reason turned out to be banal - the root certificate for SSL on the server is incorrectly installed.
It was time for the update and after reinstalling everything worked.
ps: by the way, the application worked via HTTP, but not via HTTPS...

Answer 2

Do you have https or http? over http servers simply may not process GET requests, but in phoneGap, the http protocol is probably used by default.
