Dahua DMSS App Not Loading? Here’s How to Fix It
When you need to check your security cameras, the last thing you want is for the Dahua DMSS (Digital Mobile Surveillance System) app to be stuck on the loading screen. Whether it's crashing, freezing, or simply refusing to open, this issue can prevent you from viewing your live feeds or recorded footage.
This troubleshooting guide, written in British English, will walk you through the most common reasons why the Dahua app might not be loading and provide clear, step-by-step solutions to get it working again on your smartphone or tablet.
Step 1: The Simplest Fix - Force Close and Relaunch
Often, a minor glitch can cause an app to hang. The first and easiest thing to try is a simple force close.
- On iOS (iPhone/iPad): Swipe up from the bottom of the screen to open the app switcher. Find the DMSS app preview and swipe it up and off the screen to close it.
- On Android: Go to 'Settings' > 'Apps' > 'DMSS'. Tap on the 'Force Stop' button.
After closing the app, wait a few seconds and then try opening it again. This simple restart often resolves temporary issues.
Step 2: Clear the Application Cache
The app stores temporary files in a 'cache' to help it load faster. However, this cache can sometimes become corrupted, leading to loading problems.
- On Android: Navigate to 'Settings' > 'Apps' > 'DMSS' > 'Storage'. You will see two options: 'Clear Cache' and 'Clear Data'. Start by tapping 'Clear Cache'. This will not delete your login information or settings. Relaunch the app to see if this has fixed the problem.
- On iOS: iOS does not provide a direct way to clear the cache for a single app. The equivalent action is to offload or reinstall the app (see Step 4).
Step 3: Check Your Internet Connection
The DMSS app needs a stable internet connection to communicate with your security system.
- Switch Networks: If you are on Wi-Fi, try turning it off and using your mobile data instead. If you are on mobile data, connect to a reliable Wi-Fi network. If the app loads on one network but not the other, you have identified a problem with that specific internet connection.
- Restart Your Router: If the issue seems to be with your Wi-Fi, try restarting your home router. Unplug it from power for 30 seconds and then plug it back in.
Step 4: Update or Reinstall the DMSS App
An outdated app can cause compatibility issues with your device's operating system.
- Check for Updates: Go to the Apple App Store or Google Play Store and search for "DMSS". If there is an 'Update' button, tap it to install the latest version.
- Reinstall the App: If updating doesn't work, or there is no update available, the next step is to reinstall the app.
- Uninstall: Press and hold the DMSS app icon on your home screen and select 'Uninstall' or 'Delete App'.
- Reinstall: Go back to the app store, search for "DMSS" again, and download it.
- Log In: Once installed, open the app and log in with your existing account credentials. Your devices are tied to your account and should reappear automatically.
Step 5: Check Device Permissions
The DMSS app requires certain permissions to function correctly. Ensure that you have not accidentally denied it access to essential services.
- Go to your phone's 'Settings' > 'Apps' > 'DMSS' > 'Permissions'.
- Make sure permissions for 'Storage', 'Network', and 'Camera' are enabled. If any are disabled, re-enable them and try launching the app again.
By following these troubleshooting steps, you can resolve the vast majority of issues that prevent the Dahua DMSS app from loading, ensuring you always have access to your security system when you need it.
