iOS14 always get reachable on 4G with wrong hostname

[luckyzd]

Reachability *reach = [Reachability reachabilityWithHostname:@"abcd"];
reach.reachableBlock = ^(Reachability *reachability) {
            NSLog(@"ios14 always reachable on 4G ");
};
[reach startNotifier];

iOS14 x 4G not OK
iOS14 x wifi OK
iOS13 x 4G OK
