Cannot access and reset my WD Sharespace

Hello, please help me with my Sharespace.
The device is visible on my network, can ping, but I cannot access via web browser and via LAN. Only Twonky at web can access.
Reset button pressing over 20-25sec not changing the static address to DHCP and not resetting name of the device.
Thank you so much in advance for any help.

You should contact WD Customer Support for such issue.
