Smartthings plug IM6001 wont connect

Bought three Smartthings smart plug IM6001 OTP1 but can not connect them, sits 30cm from the hub. When I insert them into sockets, it flashes blue (double flashing) but nothing more happens in the app when it is in connection mode. Got error code as shown. Have tried holding down the on / off button to try to reset but can’t see if it resets, only blue flashes, but no other color, if it should do so to confirm that it has been reset? Has smartthings hub v3 control version 2.3.3-2, software 000.043.00004.

After unplug the hub from power supply for several hours and then powered it on again i now can connect the plugs!
