Impossible to join the unleashed network (T300)

[nicola_h_berli]

Hi all!
I've got a problem. So I have three T300 (Firmware: 200.2.19....)  and and two of them can't join the unleashed network (master one).
They are in a loop... There's standing :
Founding the Unleashed Network. It may take a few minutes.
When it's finished, the browser can't build a connection up to the server and when I refresh the page it starts trying to join again but its not working.

So I tried to reset the AP's via SSH and put another Firmware on it. (200.1.9.12), with that one it's also not working.

What should I do?

Did you ensure your two slave APs were NOT a connected to the network while you setup the master?
