Apple Watch Device crashing with SandboxViolation deny(1) network-outbound - ios

Question

Im having an issue on the Apple Watch when making network calls.
It works fine on the simulator but when deployed to the device I see this in the device logs:
MyAppleWatch kernel(Sandbox)[0] : SandboxViolation: MyWatchApp(203) deny(1) network-outbound /private/var/run/mDNSResponder
The code for making the call is done using refit and works on the simulator so I would imagine it is not the cause but I will post it if necessary.
I have set these values in the Info.plist of the WatchExtensionApp (and not set them in the WatchApp as these keys )
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>my.domain.com</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
I set the WatchApp and WatchExtensionApp to:
Just at a bit of loss as to what to try next. Any help would be greatly appreciated.

Answer 1

Ok I got it working, Firstly I changed my Info.plist to:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>my.domain.com</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
</dict>
I had to change all my network calls to us NSUrlSession rather than using Refit + HttpClient. So I assume there is something in the HttpClient that watchOS doesn't like or watchos only works with NSUrlSession. Anyway here is a sample of one of my calls:
public async Task<HttpResponse> MakeCall(NSMutableUrlRequest request)
{
var result = new HttpResponse();
var config = NSUrlSessionConfiguration.DefaultSessionConfiguration;
var session = NSUrlSession.FromConfiguration(config);
var resultUser = await session.CreateDataTaskAsync(request);
var response = resultUser.Response as NSHttpUrlResponse;
if (response != null)
{
result.StatusCode = (int)response.StatusCode;
result.Content = NSString.FromData(resultUser.Data, NSStringEncoding.UTF8).ToString();
}
return result;
}
public async Task<HttpResponse> GetStuffWithParameter(string parameter, string authorization)
{
var url = new NSUrl($"https://www.domain.com/api/stuff/{parameter}");
var header = new NSMutableDictionary();
header.SetValueForKey(new NSString(authorization), new NSString("Authorization"));
header.SetValueForKey(new NSString("application/json"), new NSString("Content-Type"));
var request = new NSMutableUrlRequest(url)
{
Headers = header,
HttpMethod = "GET"
};
return await MakeCall(request);
}
public class HttpResponse
{
public int StatusCode { get; set; }
public object Content { get; set; }
}
Hope this helps.
