        When I'm trying to close the tunnel at my MacOS VPN app, I can see the error

        Error Domain=NETunnelProviderErrorDomain Code=3 "The request to set/clear the tunnel network settings failed." UserInfo={NSLocalizedDescription=The request to set/clear the tunnel network settings failed.
        
        
        

         

        Why does it happening? And how can I prevent it?

         

        Edit:

        In case I got    stopTunnelWithReason, do I still need to try and close the tunnel? or is it already done by the system?

          You should have a look at the system log; most errors like this log some details about the underlying cause.  If necessary, you can enable extra logging using the instructions on the Bug Reporting > Profiles and Logs page.

              Those are some relevant msgs I get from the extra logging:

              So is it OK to guess that after calling stopTunnelWithReason there is no need to clear the tunnel settings ?
