OneClick deployment for the Dynamics NAV 2015 windows client (Error message:A server was not found)

Hi everyone,
we have two azure servers, one for development/training and one for production.
With the same configuration and we have run the install.ps1 from the demo.
In the development environment the links are created correctly (exactly as they are when you install the demo environment) and the windows clients are accessed outside the azure environment.
In the production environment the error attached is raised when somebody tries to install the windows client. Most probably something is wrong in the NAV server but i cannot find it, if somebody can see something it would be very helpful.
The error message:
The configuration in the NAV administration is the following:

The urls populated after running the ps1 file:




If anybody can see where i have misconfigured the server, please tell.
Kind Regards
