WD Sharespace cannot access and reset

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 http 192.168.1.53:9000 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 :)
