I set up My Cloud successfully about 18 months ago and have been using it with no problems through the desktop app, and remotely through my iPhone app and have successfully backed it up to a My Book that is attached to it. But now (even though I have changed NOTHING), it can no longer be accessed through any of the WD software - not the desktop app (gets “can’t connect to this device” error), not the iPhone app (gets “Device Offline” error), not the WD Utilities software - gets “attached a supported drive” error as if it doesn’t “see” it), or the web UI 192.168.1.6 - gets a “this webpage is not available” error. The only way I can access it at all is through Windows Explorer, which does show it and its folders. But I can’t back it up, I can’t check the firmware, or even look at anything related to it, or send or get anything to or from it remotely. It is virtually useless. And I DIDN’T DO ANYTHING to any settings anywhere - it just suddenly became inaccessible.

But your router probably did, if you have the IP address allocation left as DHCP. If your router has rebooted, or the MyCloud updated its firmware, your router may have given the MyCloud a different IP address. Use your router UI to find out what IP address is allocated to the MyCloud, and then use the UI to make it always use this address (DHCP/fixed/infinite timeout or set a Static IP).
