Netfox blocks API requests on iOS 11

[Zyoma108]

I've faced with a problem that some API request fail with The request timed out error. I don't know the reason, but some requests also take longer than usual. For me, this only appears on iOS 11 and works fine on versions above.

If you use Firebase analytics it also fails:

 6.9.0 - [Firebase/Analytics][I-ACS901017] Encounter network error. Code, error: -1001, Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSErrorFailingURLStringKey=https://app-measurement.com/a, NSErrorFailingURLKey=https://app-measurement.com/a, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2103, NSLocalizedDescription=The request timed out.}
