Hi. I'm facing an issue where all AP's are losing connection and start to update configurations from controller again. I don't know what I can check to diagnose this issue. Any idea?

Thanks!

Most likely there is a firewall in between that drops the permanently open control connection.

Hi Gheist. Thanks for you help. I don't have any firewall in bettween, one of the things that I notice is that all ap's just start synchronizing again they do not restart. Any idea?

Can you count PoE consumption? Maybe they all restart. Or the electricity has some problem in general (like broken UPS)?
Yes thay reload config on restart.
Can you place one AP next to controller on same electricity to and check if that joind the configme party?

Hi. Actually the controller and Ap's are in the same electricity, I don't think they restart because when I check how long they are connected with controller it shows since yesterday for example. Is there any log where I can check the reason of this re-synchronization?

Check process list on APs - probably some useless service pushes rccd out of memory and it does not respond to controller.
Also look for rccd log in each AP...

Hi! Can you explain what means "rccd logs may reveal more". Where can I find these logs?

rccd is one of processes running on access point. It is responsible for handling control commands from controller. It writes log to local nvram unless you record it over syslog. browse to access point web page and check if you can get that log displayed.

It was what really solved the problem. None of the others solved the problem itself.
