Navigation through the 'Tunel de Somport' (FR/ES) does not work

I’m trying to create a route from FR to ES, trough the Tunel de Somport’ & station de Canfranc. For some reason, the navigation does not want to take the pass, no mather how many waypoints I add. No blocked roads etc visible in other routeplanners.
