I would have a look outside of the Aruba equipment. You may try to do a packet capture on the client and analyze the traffic.
One thing that may be causing this is if you have a firewall or transparent proxy that does HTTPS or SSL inspection. That breaks the security and may break the validation of applications if that traffic is SSL inspected.
