Lost Share Access on Mobile App

Losing access to shared folders via a mobile app—especially for cloud storage or NAS platforms like WD My Cloud, Synology, or QNAP—can be frustrating and disruptive. When a mobile app fails to access shared directories or files that were previously available, it typically indicates a change in permissions, network settings, or app configuration. Fortunately, these problems are usually fixable with a few systematic steps.

🔍 Common Causes for Lost Share Access

1. Credential or Session Expiry

Most mobile apps require you to log in using your NAS or cloud account credentials. If your login session expires or the password has changed, the app may lose access to shares.

2. Firmware or App Updates

New firmware or mobile app updates may reset certain configurations, remove saved credentials, or require new permissions.

3. Network Issues

The mobile app may be unable to find the NAS or cloud storage if:

Your device is no longer on the same local network.

The public IP or dynamic DNS settings have changed.

VPN or firewall settings are blocking access.

4. Permission Changes

If an admin has modified user access rights, renamed the share, or removed it altogether, you will no longer be able to access the shared folder.

5. App Cache Corruption

Occasionally, the mobile app’s cached data becomes corrupted, preventing access to resources.

✅ Steps to Fix Lost Share Access

1. Re-Authenticate

Start by logging out of the mobile app and logging back in. Make sure your username and password are correct, especially if they were changed recently.

2. Check Share Permissions

If you have access to the admin panel of your NAS or cloud system:

Verify that your user account still has read or write access to the share.

If you're using guest access, make sure it's still enabled.

3. Update the Mobile App

Check the app store for any updates to the mobile application. Developers often fix bugs related to connectivity and access in newer versions.

4. Clear App Cache and Data

In your phone settings:

Navigate to Apps > [Your NAS App] > Storage

Tap Clear Cache and, if necessary, Clear Data

Then reopen the app and reconfigure access.

5. Reconnect to the NAS/Cloud

In the mobile app:
