Since today I cannot access the gateway through the Phoscon app. It says:

I have reset the device and unplugged it to see if I could connect again but unfortunately not.
Deconz and deconz-gui are working fine as are the devices and scenes. It is just accessing the gateway that doesn't work.
I would like to be able to access the gateway before I update the firmware that was released on February 24th.
Any tips?
TIA
