I have a Dahua NVR at a remote cottage. When I look on my router, I can see the NVR is connected , cameras connected and through VPN can actually connect to the NVR and log in. Everything looks correct to me in the settings, but for whatever reason, none of the live views will come up, though I can see the recordings are still working. How do I get live view back up. I tried to remotely reboot the NVR, but that didn’t fix it. Any thoughts?
