There is obviously some sort of network communication issue going on between your devices. Here would be my suggestion. I’d reset the WD My Cloud and start from scratch.
- Perform a reset of the WD My Cloud via the steps at this link.
- Disable any software firewall applications on the PC.
- Turn off all network devices. Including smartTV’s, the gateway/router, and if possible any wifi devices like printers, tablets and smartphones.
- Connect one PC directly via Ethernet wire to the same router that the WD My Cloud is connected to.
- Turn on just the gateway/router and wait for it to boot up.
- Turn on the PC and wait for it to finish booting into the OS.
- Turn on (plug in) the WD My Cloud and wait for the solid blue light to appear.
- Follow all of the steps EXACTLY as outlined in: How to set up a WD My Cloud, Mirror, EX2, or EX4 drive on a network for the first time. Make sure to create at least one account. Do not make any other changes beyond what is needed to set the device up as detailed in the previous “How To” URL link.
- Access the WD My Cloud with the newly created username/password with a web browser.
- Proceed to set a Static IP in the WD My Cloud as outlined in the WD My Cloud User Manual. See Chapter 10, Network, Changing Network Mode from DHCP to Static and follow the steps EXACTLY to setup the Static IP information. Taking care to use the same network name and IP address pool as the PC that is being used to configure the WD My Cloud.
- If possible access the gateway/router administration page and set the WD My Cloud IP Address to “static” or “reserved” so the gateway/router DHCP server does not hand out that IP address to another DHCP client.
I would not try to get cute with changing things at this stage to make things more secure. I’d make sure everything was running properly before changing the network security settings to lock down the WD My Cloud.
Only when I was able to access the WD My Cloud drive constantly through Windows Explorer and via a web browser would I then proceed to configuring the WD My Cloud Desktop app and the WD Smartware software. I would not turn on any other network devices until I had the WD My Cloud working properly. Then I’d turn things on one device at a time to ensure it doesn’t interfere with the WD My Cloud.
For most people the directions above would be overkill but since you obviously have some sort of issue going on that is preventing access to the WD My Cloud, going one step at a time may help isolate or eliminate the issue preventing access to the WD My Cloud.
