Hi,@jinu123 

Thank you for posting on our business forum.

This article is only applicable to the following specific models, and your NVR model is not included in its applicable scope. We may release a new firmware update in the future to add support for this feature on your NVR model.

Regarding the "ERR CERT AUTHORITY INVALID" error message you mentioned: this error is triggered by a self-assigned TLS certificate, so it is  normal to see this prompt in the console. It does not affect the normal usage of your device, nor will it compromise your security. You may refer to this post: LAN local vigi nvr website cannot play live camera feed ssl certificate errors - Business Community

Thank you for your understanding.

The problem is if you look at the screenshot i attached, the feed is not loading in live or playback tab. It gives the error  Ch1:Load Failed.

The problem seems to be related to the certificate error.

So how do i get the Live and playback screens to load the feed and not give the error "Ch1:Load Failed."

Hi @jinu123 

Thanks for reaching out to TP-Link Business Forums.

May I double confirm if your NVR hardware is V2.2?

If it's V2.2, then you can try to upgrade it to the latest firmware V1.5.1, which now supports downloading certificates via the Web interface under Settings > System > System Configuration > Certificate Management.

You can observe if the same issue still persists.

If yes, please help collect the information below:

1. Please kindly provide your whole network topology, i.e., router - - switch - - VIGI NVR1008H - - VIGI IPC, etc., including the devices that access NVR interface. Since the certificate error appears to be caused by a mismatch between the accessed IP and the certificate, understanding your network layout will help us identify potential causes.

2. Please also provide your browser version information.

3. Please help check if the issue occurs intermittently or consistently. How often does the issue occur?

4. Please help collect console logs from your browser's developer tools, including any errors in the console tab and network requests/responses in the network tab. This information will help us identify which request is failing and the server's reply.

Thanks for your understanding and cooperation.

  @Gabriel-TP Thanks for the response
