I developed a iOS App, this App need to visit a local url. It can visit the url on iPhone 13 (iOS 15.4) and iPhone 14 Plus (iOS 16.5.1), but it can not visit the same url on iPhone 6s（iOS 15.8.1).

The error message is 'NSURLErrorDomain Code=-1009'.

1). The url can be visited by Safari on iPhone 6s, so the network of iPhone 6s is fine. 2). The Local Network has enabled in the APP settings. 3). I notice that in iPhone Settings -> WLAN -> Apps Using WLAN & Cellular, my App information can be found on iPhone 13 and iPhone 14 Plus, and can not find my App information on iPhone 6s.

How should I troubleshoot this issue? Thanks you!

Follows are full error message.

_NSURLErrorNWPathKey=unsatisfied (Denied over Wi-Fi interface), interface: en0,

This looks like a local network privacy failure where the route rule for Wi-Fi is denying this connection. I would double check the local network setting for this case.

BTW: The version of XCode is 14.3 (14E222b). iOS Deployment Target is 11.2, Minimun Deployments is iOS 11.2. The issue still exists if set iOS Deployment Target as 13 and set Minimun Deployments as iOS 13.

Error -1009 is NSURLErrorNotConnectedToInternet. This is a very generic error, with a lot of different potential causes. If you’re seeing this problem and your circumstances don’t exactly match those described by linjiework, I recommend that you start a new thread about your specific issue.

Use the App & System Services > Networking topic so that I see your new thread.
