To help you solve the issue when you can’t watch the Livestream of eufy battery cameras on eufy App. Please check the following:

1. Try connecting the phone to a different wifi or using the mobile data.

2. Check your firewall setting to see if there are any special restrictions for eufyCam. You can check the firewall setting at your router's official website. 

2. If you recently relocated the eufyCam that is not working, please try to move and adjust the camera location to get a better Wi-Fi signal.

3. Please set the HomeBase to Wi-Fi connection if possible.

4. Pull down the device list to refresh the device’s status.

5. Try to remove the eufyCam from the App and then add it again to HomeBase.

Steps in the App: Devices Tab> ... icon> Gear icon> Settings > General> HomeKit setup.
