Cannot connect WDLD directly to computer bypassing the router

Hi! I bought and adjusted my WD Book Live Duo 4 Tb. And now I try to solve a large number of problems arised. Almost nothing works as it should.
One of these problem appears when i try to connect WDLD to my notebook bypassing router using ethernet. My computer just does’t see WDLD.
Does anyone faced the same problem? Could you please help me with it?
Thank you in advance.

what is the colour of the light on the WDMBLD that shows?

You may reset the MBLD by holding its reset button for 4 seconds.  You may also reboot the computer and use WD Link to detect the drive.

You may have to setup static ip address in mbld if not in mbld and laptop. Make sure they both are in same subnet.

the color is green

i changed ip to static, it didnt help

Are you able to ping mbld from your computer?
