Starting VPN tunnel when no network available

Is there a way to programmatically get hold of this error so I can let the user know?

I don’t think so. The error coming back from

-startTunnelWithOptions:andReturnError:

reflects an initial check of the request to start the VPN. Once that request gets beyond a certain point the completion handler is called with

nil

and failures are reflected by the

status

property. It would be nice if there was an associated ‘last error’ value, but there isn’t.

It seems like a perfectly valid enhancement request though; please post your bug number, just for the record.

Thanks Quinn. I submitted RADAR 43889791 and suggested a couple of ideas...

- Anytime the OS decides to not start the extension propagate the error back to -startVPNTunnelWithOptions, or provide a method for us to get the last error. This could also be done with a tunnel status callback if that's most appropriate.

- Go ahead and start the extension and let us determine if we have a path to the server. We already handle periods of no connectivity after we're started, and it'd improve out users' experience if they didn't have to come back to our app after turning off airplane mode.

Hi , I am also facing this problem, please let me know is there any plan of this feature coming in latest updates ?

@vko4. See my response to your question on a different thread here.. Note that this falls inline with what Quinn is also recommending.
