Device with static IP not communicating, showing 0.0.0.0

I have a cluster of Aruba IAP 105's. They are setup WPA2-PSK. They allow DHCP through a server so it is disabled in the Arubas. The network is unrestricted. We don't use a MAC authentication, that I know of. 

We have multiple devices just like the ones we are having trouble with. They are Moxa Nport boxes for CNC machines. We have 15 running on the network with no issues. We are adding new ones only to find that the box connects and shows up by MAC address in the Auba Dashboard, but we are unable to communicate with it. It is showing up with an IP of 0.0.0.0  

We have verified that the Moxa's work on other wireless networks perfectly, so it isn't the box itself. Any input on why this is happening would be apprecaited, thank you.

Are these devices all being assigned the same User Role? Where do they get DHCP from, the IAP or somewhere external? I've seen clients with 0.0.0.0 due to an incorrect PSK previously.

I'm unclear about anything User Role related. 

For devices that are DHCP, they are getting it from a DC on a separate VLAN. These devices are just simple setup and run devices. No OS or anything. 

We have made sure that the key was correct, but that is good to remember.

Could you complete a dhcp debug and provide the output?

I have never connected via CLI on these APs. I am unsure how to do so.

You'll need an AP like Putty, enter the IP of the IAP you are testing with
and go from there :)

Ok great! I'll get the device we are having issues with on the correct network. 

I'll make sure I know which AP it is connected to

 

Then run the debug

I wasn't able to get output at all. The attached file shows the commands I used.

The first run is with the MAC address of the device itself, and the second is the MAC of the Access Point. 

I wasn't sure which MAC I needed so I tried both, and had similar results. 

Thoughts?

Was the client connecting to "Aruba3-WELD" when you ran the test?

Yes, It was and still is. I have it out on a mezzenine in our shop.
