Hi @Delvs 

Thanks for posting in our business forum.

Hmm, it showed failed. So, that's the whole story?

Do you have anything else to provide? Internet show up as connected, can you ping its IP address from another PC in the same LAN?

Same problem here. All network HW is TP Link, I am in the same network and can not bond my NVR to my account. Accesing cameras from different network is not working at all, only from same network everything is working except bonding. Error is: Device is offline, try again later. But of course this is nonsense, my device is online and working. I tried reset and no success. Any help please?

Make sure your NVR is connected to the Internet with the CORRECT DNS servers.

If you don't have the correct DNS servers, you cannot bind it. DNS resolution is involved in this matter. The default is 8.8.8.8 but some countries may not be able to add it.

For the network settings, if you cannot make it right, set up them in static mode, and make sure you put the correct parameters.

If you need more help, please make sure you specify the settings in the network with screenshots.
