Hi Rahul,
Can you try using a different power adapter?
Also, try to remove the power for 2 minutes from the controller then power it up.
While doing a factory reset, do you see any changes in the LED lights?
I believe the PC is also on the same subnet as per ZD's default IP.
If you still have same issue, please contact us support on the below link.
