Ran into problem connection Sonoff Zigbee Mini switch

[SVhuMMer]

Hi all! I am stuck with getting this device connected to my ZB network.

I am running HASS.io on a dedicated Ubuntu machine, in a docker, with Supervisor. Running 1.6.2.2, and using a CC2538 usb stick.

Recently connected successfully the bigger version of Sonoff zigbee switch - the ZB3 Basic. Now trying to connect the mini, and all I am getting is this:

I am thinking bricked switch, but maybe I am missing smth? Tried touchlink reset - no. 5 sec button reset does not change anything. The device is blinking led, so it shows it is in pairing mode, but is it?...
