DIAGNOSIS Live View requires a sustained, higher-bandwidth connection compared to uploading short clips. The error indicates your phone's data connection or home Wi-Fi cannot maintain the stream.
FIX First, test on a different network. Disable cellular data on your phone and connect to your home Wi-Fi. Attempt Live View. If it works, your cellular signal is the issue. If it fails, check your home internet upload speed. It must be at least 2 Mbps per concurrent Live View stream.
IF THAT DIDN'T WORK The problem may be local network congestion. Restart your router and sync module. Power cycle the camera by removing and reinserting a battery. Wait 2 minutes for full reconnection before trying Live View again.
HEADS UP Using a VPN or ad blocker on your phone can interfere with the Live View stream. Disable these services temporarily to test. The Blink app does not support Live View on some older 2.4 GHz-only Wi-Fi networks for phones.
