wifi pro DHCP troubleshooting

We have some users/devices unable to reach the Internet while connected to a private Wifi network created within the Wifi Pro portal. The problem lies within the fact that the device is unable to obtain an internal IP address via DHCP. In my situation, the majority of users have no issues. Manually assigning an IP address within the DHCP scope successfully remedies the issue.

How can I troubleshoot this issue with the small subset of users?

There are no console logs available to review any sort of configuration issue within Wifi Pro nor see a list of devices connected.
