Hello jdemo,
I am not sure what else to try that is causing the issue. If fabric attach was disabled and they were rebooted, did the AP's receive an IP on the correct VLAN they are configured for?
Guessing whatever IP is seen on the controller may be stale. If the only solution you have to recover an AP is to clear the config with the reset button, I would suggest to open a case with GTAC to investigate this further.
Thank you,
Jason
