My Cloud EX2 Ultra OS5: No Cloud connectivity
If your My Cloud EX2 Ultra OS5 device shows No Cloud connectivity, it means the NAS is working locally but cannot connect to Western Digital’s cloud services for remote access. This issue is common after router changes, firmware updates, DNS problems, or firewall restrictions. The good news is that most cloud connectivity problems can be resolved with proper network checks.
First, confirm that your My Cloud EX2 Ultra is connected to the internet. Log in to the dashboard by typing the device’s local IP address into your browser. Go to Settings and check the Network status. Make sure it shows “Connected” and displays a valid IP address, gateway, and DNS server. If any of these fields are missing, restart your router and the NAS device. Power off the NAS, unplug it for one minute, then restart both the router and the device.
Next, verify that your internet connection is active. Try browsing websites from a computer on the same network. If the internet works but cloud access still fails, check your router settings. Ensure that UPnP (Universal Plug and Play) is enabled. WD cloud services rely on proper port mapping, and disabled UPnP can block remote connectivity. Also confirm that no firewall rules are blocking outbound connections.
DNS configuration is another common cause. In your NAS dashboard, go to Network settings and set DNS manually to a public DNS server such as 8.8.8.8 and 8.8.4.4. Save settings and reboot the device. Incorrect DNS entries often prevent the device from reaching WD cloud servers.
Make sure your My Cloud EX2 Ultra is running the latest OS5 firmware. Go to Settings, then Firmware Update, and check for updates. Installing the latest version ensures compatibility with WD cloud infrastructure.
Also verify your WD account sign-in status. Under Cloud Access, ensure the device is properly registered to your WD account. If it shows disconnected, try logging out and logging back in. You may need to re-enable cloud access for each user.
If the issue persists, perform a 4-second reset using the reset button on the back of the device. This does not erase data but refreshes network settings. Avoid performing a full factory reset unless absolutely necessary.
In most cases, No Cloud connectivity on My Cloud EX2 Ultra OS5 is related to router configuration, DNS errors, or account authentication issues. Systematic troubleshooting usually restores remote access quickly without affecting stored data.
