Why the Live view shows ‘Authentication failed’ in Video Security App?
The VRM and port 443 is blocking the Live view authentication when the Video playback is unchecked.
If you connect the computer/ phone/ tablet running the Video Security App (VSC) to the local network, you can connect to the site using the Public IP: 443 and you can view Live video with no issues. The problem only occurs if it is an actual remote connection.
Therefore, this works as designed.
Short explanation: VSC connects directly to the VRM after authentication hand off using the BVMS credentials configured. VRM is the sole provider of video through the single configured port that VSC uses to connect. When live view is requested, you are actually seeing the last recorded frames. You are NOT being redirected to the camera since VRM has no method of tunneling live view through itself to a remote client.
VRM user groups does not have the same granularity as BVMS If playback is not allowed, then VRM will not allow access hence you cannot even login.
This is by design and cannot be changed due to the architecture.
Using a single port connection via SSH with Operator Client is the only current viable solution if the end user wishes to connect remotely and to impose restrictions on playback.
Remember that the SSH service must be manually installed if it was not during a previous installation or upgrade.
