Doorbell Error Messages

Use this article to troubleshoot error messages in the app relating to your video doorbell.

Network errors

Doorbell Offline error

Your first step should be to check if your Wi-Fi is working because the video doorbell requires Wi-Fi to communicate. 

If you have verified your local Wi-Fi network is working, try the following:

  • Reset your router. If your Wi-Fi network is slow or stops intermittently, it can help to reset your Wi-Fi router. 
  • Check your system requirements. 
  • Check the batteries. In Event Response mode, the batteries may deplete faster than when the doorbell is connected to powered wiring, or on a system with a Sync Module. Perform a power reset of the doorbell by removing the batteries for 5 seconds and then re-insert them. Wait for another 30 seconds to see if the doorbell connects.

If none of these tips resolve your issue, use the following steps for additional troubleshooting information. 

Tap the Doorbell Offline message and you will be given two options: Change Wi-Fi or Delete Doorbell. Use the sections below for guidance on how to to follow through with these steps.

Note: If your doorbell is currently mounted, you must remove it from its mounting plate for both of these options.



Change Wi-Fi of a Blink Video Doorbell

To connect your Blink Video Doorbell to a new Wi-Fi network, or reconnect to your existing network, you need the doorbell and the Blink app.

If you are seeing a "Doorbell Offline" message, tap the banner and you will be guided to change the Wi-Fi network.


Electric Shock Risk: If your doorbell is connected to powered wiring, there is a risk of electric shock when the doorbell is removed form its back plate. Live wires can cause injury if you connect them together by touching with skin, or a conductive object like a steel screwdriver.

  1. Tap the doorbell's Device Settings blink app settings screen on the home screen and then select General Settings.
  2. Tap Change Wi-Fi at the bottom of the screen then complete the steps.

Other Troubleshooting steps

Use these steps if you're having difficulty getting your video doorbell online.

What if my doorbell connects to a Sync Module?

When your doorbell is connected to a system managed by a Sync Module and it stops being detected, you receive a notification in the app and an email (if you have email notifications selected).


  1. Use the included key to unlock the doorbell from its mount.
  2. Power reset the doorbell by removing the batteries for 5 seconds and then re-insert them. Wait for another 30 seconds, then test the doorbell to see if it is connected.
  3. Move the Sync Module closer to the doorbell for more reliable signal strength and communication.
  4. Replace the batteries with two new, AA 1.5 volt Lithium non-rechargeable batteries. Increased use, and extended Live View sessions may use batteries faster than expected. 

What if my doorbell connects to wiring only?

When we detect that the doorbell is no longer online, you receive a message in the app and by email, that reads: "The connection to your doorbell camera seems to have been dropped. Please check that your Wi-Fi internet and power supply are working to your Blink Doorbell."


  1. Check that your doorbell is attached to the wall plate and that the main circuit breaker is turned back on.
  2. Sometimes home wiring may be old or not working. This device does not work with broken or low powered wiring and you may need to seek advice from a professional about the wiring in your home. 
  3. Try replacing the batteries. Even if the Video Doorbell is connected to wires, batteries are required to be installed at all times. Replace the existing batteries with two new, AA 1.5 volt Lithium non-rechargeable batteries. 
    • Adding the doorbell to a Sync Module system increases average battery life to 2 years.

Other Error Messages

If adding a Sync Module does not complete as described, the following error messages might appear.

Doorbell not found

This screen appears after an unsuccessful attempt to join the Wi-Fi network.
To make sure the doorbell is ready for connection, remove and replace the batteries to restart the blinking Red LED.

Sync Module 2 failed to connect

This screen may appear if the Wi-Fi password was entered incorrectly. Make sure you have the correct password, and tap "Retry" to attempt to connect again.

Sync Module 2 data is bad

This screen may appear if you have already installed your Sync Module and tried to delete it in order to add it to the doorbell system. Follow the instructions to reset your Sync Module and prepare to install it again.

Delete doorbell

If all else fails, delete the doorbell from your Blink system.

  1. Tap Device Settings  > General Settings
  2. Tap Delete Device.
  3. A confirmation message appears. Tap DELETE to remove the doorbell. 
  4. After you tap DELETE, you will receive an email confirming the device was deleted from your account.

After your doorbell is removed from your account, re-add it back to the account. Learn more about setting up your Blink Video Doorbell‍.


If these steps do not get your doorbell connect to the Blink servers, contact Customer Support.
