I posted this over in hardware prior but think this actually might be the proper board, any help is appreciated. Thanks in advance.

Hello Everyone,

Looking for some feedback and hopefully a solution to a problem we are seeing with the new LtAP mini LTE kit-US , the WPA2 AES password is failing , the client will attempt to enter the correct password and the router will client device will report an incorrect password response. Changing the SSID (not the password) temporarily corrects the problem. Is anyone else experiencing this problem and / or have a solution? For us it isn't a one off , we have many clients reporting this issue. We have tried changing the pre-exchange-key timeout from 5m to 1hr, no luck.,Below is a verbose export of a units wireless settings :
