Hi all,
Recently encountered a problem, the AP will suddenly be collectively disconnected, and the controller cannot be managed by logging in to the web. At the beginning, it took about 1 hour to complete the ap registration. Now the registration is completed automatically in about 10 minutes. It appears once a week on average, and it has appeared nearly seven or eight times so far.
There are more than 40 APs, some of which are older models, 1200, 1400, 1600, and the controller is 2504.
The following is the log record of the most recent failure. Someone reported that there was no network at 11:40 on August 3, and related screenshots at that time.192.168.52.52 is the AC management address. There are many types of error records in the log.
The important point is that wireless and wired share the same switch and divide different VLANs. When the AP is disconnected, it is normal for the wired network.
Can you help us find out what causes all APs to be offline collectively?
Sorry for everyone. I'm so busy that I forgot to reply.
In fact, we didn't do anything except reclassify all APs into a new VLAN, and the AC management address did not change.
As for the reason is still unclear, it may be related to the confusion of VLAN management of access layer switch.

- Looks like you may have some sort of storm broadcasting issue (e.g.) at times. Have a setup in place where network traffic can be monitored and reviewed constantly.

What firmware is the controller running on?

Agree with @Scott Fella and update the firmware of the WLC.
