Greeting from CommScope/Ruckus. As per the issue described you would need to open a support case to enable additional debug on the AP's and isolate the root cause.
1) Please open a new case either from WEB Portal.
2) Please reach out to below and a rep would help you in opening a ticket.
Note : You can provide AP support log and Network topology (switch model and version) where AP's are connected to for initial investigation.
