Hi there! I understand you haven't been receiving notifications from the Hik-Connect app since March 27, and it's still not working after 24 hours. Let's work together to troubleshoot this issue.

First, I’d like to clarify a few details to help us address the problem effectively:

1. Have you recently made any changes to the app settings or your device's notification settings?
2. Are you using the Hik-Connect app with an NVR (Network Video Recorder), and if so, is it connected and online?
3. Have you checked if notifications are enabled within the Hik-Connect app itself?

Once I have a bit more information, I can guide you through some steps to get those notifications working again!

1. Not made any changes.
2. Using it with a DVR.
3. Yes notifications are enabled.

Thanks for your quick responses! Since you’ve confirmed that no changes were made, notifications are enabled, and you’re using the app with a DVR, let’s check the DVR settings to ensure everything is configured correctly for notifications.

1. Check DVR Settings:
- Access your DVR settings directly.
- Navigate to the "Event" or "Alarm" section.
- Look for an option called "Notify Surveillance Centre" or similar. Make sure this option is checked. This allows the DVR to send notifications to the connected app.

2. Restart the App and Device:
- Close the Hik-Connect app completely and reopen it.
- If that doesn’t work, restart your Android device. Sometimes a simple restart can help with connectivity issues.

3. Check for Software Updates:
- Ensure that both your Hik-Connect app and your DVR firmware are up to date. Sometimes, updates can resolve underlying bugs affecting notifications.

4. Check Phone Notification Settings:
- Go to your phone’s “Settings,” then “Apps” or “Applications.”
- Find and select the Hik-Connect app.
- Ensure that notifications are allowed here as well.

5. Test Notifications:
- After checking and updating the settings, you can perform a test by triggering an event (like motion detection) on your DVR to check if you receive the notification in the app.

Let me know how these steps go, and if you still experience issues, we can look into advanced troubleshooting together!

I've already done all the checks stated above.

Thank you for your patience! Since you have already gone through the initial troubleshooting steps, let's look into some other possibilities that might be causing the issue with notifications in the Hik-Connect app.

1. Check Network Settings on the DVR:
- Go to your DVR settings.
- Navigate to “Settings” > “Network.” Check the IP address, Gateway, and DNS settings to ensure they are correct. If your network settings aren’t configured properly, it may prevent notifications from going through.1

2. Re-enable Hik-Connect Access:
- In your DVR settings, go to “Platform Access” or a similar option. Ensure that Hik-Connect is enabled and check if the verification code is correct. Sometimes re-enabling the function can help reconnect the app notifications to the DVR.1

3. Test Connectivity:
- Run a connectivity test by pinging the Hik-Connect server. If you're comfortable doing this, you can use a command prompt or terminal on your computer and ping the following address: dev.hik-connect.com. If the server is reachable, you should receive replies; if not, it may indicate a network issue.1

4. Reinstall the Hik-Connect App:
- If nothing else works, uninstall the Hik-Connect app completely from your Android device and then reinstall it from the Google Play Store. This can help resolve any underlying app issues that may not be evident in simple troubleshooting.

5. Contact Support:
- If you continue to face this issue after these checks, it may be beneficial to reach out to Hikvision support via email: [email protected]. They can provide additional assistance specific to your DVR model and situation.
