How to Fix Synology App Not Working Issue?

The Synology Photos app is a versatile tool for managing and sharing your photos. You can use the app with DSM 7.2 or higher. However, like any software, it can encounter issues that disrupt its functionality. This guide provides a detailed approach to diagnosing and resolving problems with the Synology Photos app to ensure a smooth experience.

Fixed: Synology Photos App Not Working

  1. Check Device Compatibility

Before diving into complex solutions, ensure that your device meets the necessary requirements for the Synology Photos app. Verify that your mobile device or computer is running a supported operating system version, and check if the app itself is updated to the latest version available from the App Store or Google Play Store.

  1. Verify Network Connection

The Synology Photos app relies on a stable network connection to communicate with your Synology NAS. Ensure that your device is connected to the same network as your NAS. Test your internet connection by accessing other online services. If there are issues with connectivity, restarting your router and modem can often resolve them.

  1. Check DSM Version

Your Synology NAS should be running the latest version of DiskStation Manager (DSM). Log in to DSM through a web browser and navigate to Control Panel > Update & Restore. If an update is available, follow the prompts to install it. An outdated DSM version can cause compatibility issues with the Synology Photos app.

  1. User Permissions and Access

User permissions can sometimes prevent the Synology Photos app from functioning properly. Verify that the user account you are using has the necessary permissions to access the Synology Photos app and the relevant photo libraries. Go to Control Panel > User and check the permissions for your user account under the Application and Shared Folder tabs.

The Synology Photos app accesses photos stored in specific shared folders. Ensure that these folders have the correct permissions set. Navigate to Control Panel > Shared Folder, select the folder where your photos are stored, and click on Edit. Under the Permissions tab, make sure your user account has read and write access.

  1. Fix Sync Problems

If your photos are not syncing correctly, the problem might lie in the sync settings. Open the Synology Photos app on your device and go to the settings menu. Ensure that the sync options are enabled and configured correctly. For mobile devices, check if the app has the necessary permissions to access your photo library.

  1. Resolve App Crashes

App crashes can be caused by a variety of factors, including software bugs and device-specific issues. Start by force-closing the Synology Photos app and reopening it. If the problem persists, try reinstalling the app. Additionally, clearing the app’s cache and data can sometimes resolve crash issues. On Android, this can be done via Settings > Apps > Synology Photos > Storage > Clear Cache and Clear Data.

  1. Checking System Logs

System logs can provide insights into what might be causing the Synology Photos app to malfunction. Access the logs through DSM by going to Control Panel > Log Center. Look for any error messages or warnings related to Synology Photos. These logs can help identify issues related to file access, permissions, or system resources.

  1. Testing Network Configuration

Advanced network configurations, such as custom DNS settings, firewalls, and VPNs, can interfere with the Synology Photos app. Temporarily disable these configurations to see if the app starts working. If it does, you may need to adjust your network settings to allow proper communication between your device and the Synology NAS.


Addressing issues with the Synology Photos app involves a combination of basic troubleshooting steps, verifying configurations, and advanced diagnostics. By ensuring your device compatibility, network connection, proper NAS configuration, and correct user permissions, you can resolve most issues that prevent the app from functioning correctly.
