Client Isolation is on, even though cloud manager says it's not
I've got a network here that it worked fine for about 2 years, then all of a sudden, devices couldn't talk to each other. It was behaving just like client isolation was on. I verified in cloud manager that it was indeed off. I turned it on, then off again, and the devices worked fine. THis time however it only lasted about 3 weeks, and the same symptoms. Turning client isolation on then off again resolved, but now that it's happened twice, I'd like to know what we can do for permanent fix.
