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.

My Cloud EX2 Ultra OS5: No Cloud connectivity

If the Files app on iPadOS does not copy subfolders from your WD My Cloud EX2 Ultra share, the issue is usually related to SMB compatibility, permissions, large directory structures, or iPadOS limitations rather than a hardware fault. This problem commonly appears when you try to copy a main folder that contains multiple nested subfolders and the transfer either fails silently, stops midway, or copies only the top-level folder without its contents.One of the most common causes is SMB protocol compatibility. The EX2 Ultra supports multiple SMB versions, but iPadOS works best with SMB2 or SMB3. If the NAS is using older SMB settings, subfolder transfers may fail. Log in to your EX2 Ultra dashboard from a web browser, go to Settings, then Network or File Sharing, and ensure SMB2 or SMB3 is enabled. After changing the setting, reboot both the NAS and your router before testing again.Permissions are another major factor. Even if you can see folders in the Files app, you might not have full read/write permissions for nested directories. Check the share settings in the EX2 Ultra dashboard. Confirm that the user account you are using on the iPad has read and write access not only to the main share but also to all subfolders inside it. If necessary, temporarily set the share to Public to test whether permissions are causing the issue.Large folder structures can also cause copy failures. iPadOS sometimes struggles when copying directories containing hundreds of subfolders or thousands of files. Instead of copying the entire parent folder at once, try copying smaller subfolders individually. This reduces memory strain on the Files app and often resolves incomplete transfers.Network stability matters as well. If the WiFi connection drops even briefly, the Files app may stop copying without displaying a clear error. Make sure your iPad is connected to a stable 5GHz WiFi network if available. Avoid switching apps during the transfer, as iPadOS may suspend background file operations.Another possible cause is how the EX2 Ultra handles metadata and file attributes. Some NAS systems store hidden system files or extended attributes that iPadOS cannot process correctly. If you suspect this, try copying the same folder to a Mac or Windows PC first. If the copy works there but fails on the iPad, the issue is likely iPadOS compatibility rather than the NAS itself.You should also check the firmware version of the EX2 Ultra. Older firmware versions may have SMB bugs affecting Apple devices. Log in to the NAS dashboard and verify that it is running the latest OS5 firmware. Updating firmware can resolve compatibility problems with modern iPadOS versions.As a workaround, consider using a third-party file manager app from the App Store that supports advanced SMB handling instead of relying solely on the native Files app. Some third-party apps manage recursive directory copying more reliably than the built-in tool.If copying is still unreliable, another solution is to compress the folder into a ZIP file on the NAS using a computer first. Then copy the single ZIP file to your iPad and extract it locally. This avoids subfolder recursion issues during transfer.In most cases, enabling SMB2/SMB3, verifying permissions, breaking large copies into smaller chunks, and ensuring firmware is up to date will resolve the issue. The EX2 Ultra hardware is generally stable, and the limitation typically lies in how iPadOS handles network file transfers rather than a failure of the NAS itself.
