    }

Steps to Reproduce:
1) Make a http request while there is a network issue(Example- wifi goes and comes back)
2) Make the app go in background.
3) After 20-30 seconds, launch the app again (make sure you have wifi connection when you are about to launch the app)
4) App crash immediately.

Expected Results:
App should not crash when it comes from background while having network issues.

Actual Results:
App crash in DNSServiceProcessResult() with SIGSEGV - segmentation violation
