It must be a bug in the software. Today I reset all 5 ap's. Then I booted one ap, connected to the configure me wifi, and opened unleashed.ruckuswireless.com in my browser. I got into the first configuration page. The version is 220.127.116.11.92 (see image00.png). After that I went through all steps (see image01 to 05). After that the wifi is indeed working (with still only one ap). But if I try to open unleashed.ruckuswireless.com again in my browser it won't get in, and also the app gives me the message "you are not connected to Unleashed network" (see image06.png). I can add the other 4 ap's and they will all work. But I cannot make any changes to the configuration.
