p.authenticationMethod = NEVPNIKEAuthenticationMethodSharedSecret; p.sharedSecretReference = [self searchKeychainCopyMatching:@"PSK"];
Failed to create IKEV2 using PSK, and the following error message is displayed:
Start VPN failed: [The operation couldn’t be completed. (NEVPNErrorDomain error 1.)]
May I ask what the reason is?
