Hello everyone ! I have solved my problem and now I will tell you how. First of all I wanted to thank @meaton for the help and assistance, thank you! So let's get started. The concept of a vpn application was arranged in the following way: Json comes to me from the server, one of the fields of which contains an .opvn file in string format. In my case, passwords and username are not required (! THIS IS IMPORTANT), I only use the certificate itself. The main mistake was my non-fundamental knowledge of the principles of the protocols. When I received .opvn that value for the 'serverAddress' property I took opposite the 'remote' field. I took only the first part ! This was the main mistake. objective-c // Example of the file I received: client remote 32.185.104.19 53513 resolv-retry infinite nobind setenv opt block-outside-dns script-security 2 dhcp-option DNS 1.1.1.1 I extracted only "32.185.104.19", and I need everything at once (along with a space) "32.185.104.19 53513". Once again, I used the OpenVPNAdapter external library.

Dear @meaton, I just submitted my application. I was assigned the code: Follow-up: 762793516 Regards, @iosdev000

You're right. I'm currently working on submitting my code for review in TSI.

Dear @meaton, I implemented os_log, but it didn't help me. This is an anomaly, logs are not output. Show my code here: objective-c @interface PacketTunnelProvider () @property os_log_t log; @end In 'os_log_create' I pass my extension bundleID and Target name. objective-c (id) init {     if( self = [super init] ) {         self.log = os_log_create("site.com.MyVPN.PacketTunnel", "PacketTunnel");         os_log_debug(self.log, "[PacketTunnelProvider][init]");     }     return self; } objective-c(void)handleAppMessage:(NSData *)messageData completionHandler:(void (^)(NSData * _Nullable))completionHandler{     os_log_debug(self.log, "handleAppMessage"); } Even i tried use 'OS_LOG_DEFAULT' objective-c     os_log_debug(OS_LOG_DEFAULT, "handleAppMessage");

@meaton, I followed your recommendation and removed PersonalVPN. But it didn't help me. All the methods I call in this sequence: objective-c(void)initProvider {     __weak typeof(self) weak = self;     // (1) load     [NETunnelProviderManager loadAllFromPreferencesWithCompletionHandler:^(NSArrayNETunnelProviderManager** _Nullable managers, NSError* _Nullable error) {         if(error){             NSLog(@"loadAllFromPreferencesWithCompletionHandler error: %@",error); return;         }         // (2) create providerProtocol         NETunnelProviderProtocol *tunel = [[NETunnelProviderProtocol alloc] init];         tunel.providerBundleIdentifier  = @"mySite.com.MyVPN.PacketTunnel";         tunel.providerConfiguration     = @{ @"ovpn" : self.configData };         tunel.serverAddress             = @"vpn.mySite.com";         tunel.disconnectOnSleep         = NO;         // (3) create providerManager         weak.providerManager = managers.firstObject ? managers.firstObject : [NETunnelProviderManager new];         weak.providerManager.protocolConfiguration = tunel;         weak.providerManager.localizedDescription  = @"MYVPN";         [weak.providerManager setEnabled:YES];         // (4) save configuration         [weak.providerManager saveToPreferencesWithCompletionHandler:^(NSError *error) {             NSLog(@"%@", (error) ? @"Saved with error" : @"Save successfully");             if(error) return;                          // (5) load again             [weak.providerManager loadFromPreferencesWithCompletionHandler:^(NSError * _Nullable error) {                 if(error){                      NSLog(@"loadFromPreferencesWithCompletionHandler error: %@",error); return;                 }                 // (6) connect                 [weak connection];             }];         }];     }]; } Selector for UIButton objective-c (void)connection {         __weak typeof(self) weak = self;     [self.providerManager loadFromPreferencesWithCompletionHandler:^(NSError * _Nullable error) {         if(!error){             [weak.providerManager.connection startVPNTunnelAndReturnError:&error];             if(error) {                 NSLog(@"Start error: %@", error.localizedDescription);             }else{                 NSLog(@"Connection established!");             }         }else{             NSLog(@"connection error:%@",error);         }     }]; } My Info.plist and .entitlements configurations (link to images). objective-c https://ibb.co/k22ksfj https://ibb.co/GpYbZCs https://ibb.co/9sSkr5y P.S. Before building application, I press "Debug""Attach to process by PID"(Select 'PacketTunnel'). Then I run application. But my NSLog in PacketTunnelProviders don't print (!). I don't know what I must do....

 @meaton Hmm, I suspect that you have mixed up the sequence of actions. Can you give a pseudo or real code? Sorry, but step 6 can't be done. Get the NEVPNConnection from the NETunnelProviderSession inside of the callback from (5) and call startTunnelWithOptions. NETunnelProviderSession hasn't method, that can return 'NEVPNConnection'. objective-c @interface NETunnelProviderSession : NEVPNConnection (BOOL)startTunnelWithOptions:(nullable NSDictionaryNSString *,id *)options andReturnError:(NSError **)error; (void)stopTunnel; (BOOL)sendProviderMessage:(NSData *)messageData returnError:(NSError **)error responseHandler:(nullable void (^)( NSData * __nullable responseData))responseHandler; @end

Hi, I have the same problem - https://developer.apple.com/forums/thread/674644 and haven't found a solution yet. Did you manage to solve it? I think the main problem is in certificates and identifiers. Try updating your Info. plist by adding new values there, as shown here: https://developer.apple.com/forums/thread/669690?answerId=653497022#653497022 Please, if you manage to solve this problem, let me know:) Also, for a more in-depth study of this problem, I'm going to review these videos: Watch them too if you haven't solved this problem yet.
