What to do? Already connected WD directly to the computer via an ethernet cable, I tried to log in via a local (local 192.168.0.2 IP) and through a new one. I wrote to them in technical support, they have not answered yet. The docks say that the reset button is 4 seconds. hold and reset passwords, and the data will remain. But there is valuable data there, and if there is even the slightest chance of their deletion, then it is better not to press the reset button.
from comment:
On the computer, it is necessary to automatically receive the address - (then goes to the router), and on the router there is already a static 172.82.2.3 (from the same place I put on the NAS) the same address 172.82.2.3 and the same mask. PS: I also suspect that the IP conflict is because on 172.82.2.3 - the router opens, and on 172.82.2.3/UI nothing opens. (Although earlier it was the address of WD - 192.168.0.2/UI).
