Wd My Cloud Ex2 Ultra something is not visible from windows and MAC in the same local network

probably after a wakeup from standby my windows laptop and my macbook lost the local network connection with the nas.
I’m able to reach it open a web browser, but I don’t see it available into file explorer (windows) and Finder (MacOSx).
I need to reboot it using its web interface…after that it come back available for file transfer.
Where can be the issue?
Thanks a lot
