I can't ping My Book Live, but it refuses network connections

Hi,

I have been using My Book Live with no issues for years, but 3 days ago I was not able to read its contents from any home computer on the home network. I can ping it’s IP address

but is not visible on my home network. When I try to open it’s home web page I get a message saying the device refused the connection:

When I turn power off/on the LED starts in solid blue, after some seconds it changed to solid green.

Any suggestion?

Thank you.
