QTLocation: RouteModel Update Error Undefined

I am using QT 5.6.0 with Qtcreator 3.6.1 on ubuntu 14.04 LTS 64bits.
I used the example mapviewer from installation directory.
Without changing the code, I am not able to load a route.
I am trying to Find a route from openstreetMap so I have a RouteModel and a RouteQuery. I added waypoints to the Routequery, change the travelModes to RouteQuery.CarTravel and the routeOptimizations to RouteQuery.fastestRoute. And then, I dit routeModel.update().

My problem is that the status change (onStatusChanged) to undefined error. First the status is ModelRoute.loading and then the status goes to RouteModel.Error. When I print the errorString, it is written as undefined.

So how can I correct the problem ? Is there a way to obtain more information about the error ?

If I look on the application output, I can see 2 warnings but I am not sure it is the cause : qt.network.ssl: QSslSocket: cannot resolve SSLv2_client_method qt.network.ssl: QSslSocket: cannot resolve SSLv2_server_method

Do you think it could be the cause of the error ? If Yes, how to correct it ?
Can it be because of the proxy ? How to know ?

Thank you in advance for your answer.

Yes, if the routing provider URL is using HTTPS. If so then you need to install the OpenSSL run time libraries to match your system. https://wiki.openssl.org/index.php/Binaries

Can it be because of the proxy ? How to know ?

Yes. If a browser on the same machine needs a proxy to access the internet then your application will likely need the same proxy set.
