so the blueprint that the logical template is mapped to definitely gets an IP address when provisioned in vRA. if it does and it can ping its gateway and the iaas model manager server, then check the logical template is mapped to the correct blueprint. If using linked clones, make sure you have run dara collections and you've selected the right snapshot. No reason why the app services VM should get an IP if a vRA VM does. I would triple check config.
