These help codes mean that the app had trouble connecting to your camera.

Troubleshooting 

  1. Close the app.
  2. Use the instructions in this article to restart your camera.
  3. Make sure your phone’s Wi-Fi and Bluetooth are turned on, and that it’s connected to the same Wi-Fi network you want to use for your camera.
  4. Try to set up your camera again in the app.
  5. If the help code still appears, and you’re using the app on a phone, reboot your device and check if that fixes the issue.
  6. If you still can’t set up your camera, contact support.

There was a Bluetooth connection problem

Help codes:

C107 ∙ C111 ∙ C112 ∙ C113 ∙ C114 ∙ C115 ∙ C116 ∙ C117 ∙ C118 ∙ C201 ∙ C203 ∙ C204 ∙ C212 ∙ C234 ∙ C235 ∙ C236 ∙ C237 ∙ C238 ∙ C239 ∙ NC021 ∙ NC022 ∙ NC023

These errors mean your camera couldn’t connect to your phone through Bluetooth. You’ll need to make sure Bluetooth is working and is enabled on your device.

Troubleshooting 

  1. Quit the Nest app.
  2. Use the instructions in this article to restart your camera.
  3. On your phone, switch Bluetooth off and then on again to reset the connection. Make sure that Bluetooth is on when you’re done.
  4. On rare occasions, your phone might not let you turn on Bluetooth. If you run into this issue, try to reboot your device. Otherwise, skip to the next step.
  5. After turning on Bluetooth, bring your phone within 12 inches (0.3 m) of your camera, and keep it there until setup is complete to help reduce wireless interference that may disrupt the Bluetooth connection.
  6. Now, try to set up your camera again.
  7. If you still can’t set up your camera, try a different phone if you have one.
  8. If the Nest app displays a Bluetooth error again, reboot your phone if you haven’t already. Then try to set up your camera again.

If all else fails, you can try to set up your camera without using Bluetooth if you have one of the following cameras:

  • You might want to use a different phone to set up your camera. You’ll need to install the Nest app on the other device and then follow the steps in the app to set up your camera.

    • Nest Cam Outdoor
    • Nest Cam Indoor
    • Dropcam

Your camera couldn’t connect to your other Nest product(s)

Help codes:

NC013 ∙ NC014 ∙ NC018 ∙ NC024 ∙ NC030

During setup, your Nest camera or doorbell will try to get Wi-Fi information from the other Nest product in your home. Your camera or doorbell will know there’s another Nest product in your home because it will find the product in the Home app or Nest app.

If your camera or doorbell can’t connect to the other Nest product, it won’t be able to get the information it needs to complete setup. When it can’t connect, one of these help codes may appear.

Troubleshooting 

1. Restart your camera or doorbell

Use the instructions in this article to restart your camera. Then return to these steps and go to step 2.

2. Connect to the same Wi-Fi network

  1. Connect your phone to the same Wi-Fi network as your existing Nest product(s).
  2. Try to set up your camera or doorbell again while your phone is on the same network.

    • After completing camera or doorbell setup, you can connect your phone to a different Wi-Fi network if you like.

  3. If you’re still getting the same error after trying the steps above, restart your camera or doorbell again and continue troubleshooting below.

3. Move your products closer together

During setup, your new camera or doorbell will try to connect to one of the following existing Nest products in your home:

  • A Google Nest camera or doorbell
  • Google Nest Protect smoke and CO alarm
  • Google Nest Guard (the main part of the Google Nest Secure alarm system)

Note: Google Nest thermostats, Google Nest Detects, Google Nest Tags, and other Nest camera models don’t participate in setup as described above.

Here’s how to help them connect:

  1. Temporarily bring your camera or doorbell and your other Nest product within about 30 feet (10 m) of each other.

    • For a Nest camera, try to bring your camera closer to your other Nest product. You might need to plug your camera into an outlet that’s closer to the other product.
    • For a Nest Doorbell wired, try to bring your other Nest product closer to your doorbell.
  2. When your products are closer together, go through setup again.

  3. If that doesn’t work, restart your camera or doorbell. Then bring your camera or doorbell and your other Nest product within a few feet (1 m) of each other and go through setup again.

  4. Once you’ve added your camera or doorbell to the app and have completed setup, you can install your products farther away from each other. They only need to be close together during setup.

Your internet security settings prevent your camera from connecting

Help codes:

C209 ∙ C229 ∙ C230 ∙ C231 ∙ C232 ∙ C233 ∙ NC008 ∙ NC009

Your doorbell went idle and you can't complete setup

Help code:

NC019

Your camera needs to be awake to connect to Wi-Fi and complete setup in the app. Typically, if your camera’s status light turns off during setup, your camera is no longer awake and you won’t be able to add it to the app.

Troubleshooting

  1. Close the app.
  2. Follow instructions to factory reset your camera.

Your doorbell may have previous settings

Help code:

NC003

When this error appears, it means the app thinks that your Nest doorbell has some previous settings on it. You’ll get the message "Reset your Nest Doorbell."

Troubleshooting 

Reset your doorbell to factory defaults:

Nest Doorbell wired

  1. If your doorbell is already attached to the wall, you’ll need to take it off. Use the release tool that was included with the doorbell, a paperclip, or a thumbtack.

  2. Insert it into the hole at the bottom of the doorbell and pull it off the base.
    Tip: Don’t unscrew the wires attached to the back of your doorbell if it's hardwired to your home's power.

  3. Hold down 2 buttons on your doorbell for about 10 seconds:

    • Hold down the reset button on the back (use the the release tool or a thumbtack)
    • At the same time, hold down the big doorbell button on the front
  4. While holding the buttons, your camera will chime and its light ring will start spinning blue, then flash yellow, and then all the lights will turn off.

  5. Release the 2 buttons.

  6. The factory reset is complete when your camera chimes and the light ring starts slowly pulsing blue.

Once your doorbell has been reset to factory defaults, you can add the camera back to the app.
