HC3 Zigbee adding mode not working?

[ErikV 1]

I'm unable to add Zigbee devices to my HC3. When I click to add a Zigbee device, the HC3 console shows Waiting for adding process to start. After 3 minutes, it updates to Timeout for adding devices expired. 

 

I'm using two different Aqara Temperature and Humidity sensors and both have the same results. Fibaro support keeps telling me to try again or reset the Aqara sensor, but I'm suspicious of the HC3 itself. The messages in the HC3 console seem to imply that the HC3 is trying to go into adding mode, but that it hangs there. Can anyone confirm this? I'd be interested to learn what the console says when all goes as it should.

I have successfully added the sensor to my system, but I had to do multiple attempts, there is a suggestion at this this. Not sure which procedure helped for me.

To add to the system I used and external source of 3.7V

Pushed more than 5sec to reset (3 blue led blinking of confirmation) than I randon push the button until it wad added.
