Hi GCredit,
Could you Factory reset the AP once and try connecting back again?
To factory reset the AP please find Factory Reset button on back of AP and use paper clip or pin, press and hold the button for about 7-10 seconds with power on.
The AP would try to connect to SZ again, now the AP would get the AP password configuration that you set on the SZ as well.
Once AP boots up SSH into the AP and run command "get scg".
If still there is an issue, check on events to see if there is some error or logs pertaining to AP/SZ connection, based upon it contact support they should be able to resolve it over a remote session.
