I've got a Dahua DHI-NVR5208-8P-4KS2E NVR. I cannot access the config of any Dahua IP CAM connected to physical Port 1 of the NVR. I move the same IP CAM to another port and it works fine. On Port 1, when I click on the blue IE sign, new tab on the browser is opened with the URL - . I have noticed that for other ports, when I click on this blue IE sign the URL is . Any idea why this is different compared to port 1? The other difference I've noticed is that on the NVR Camera List tab where I can see all CAMs, the port for CAM on physical port 1 says 3777 while other ports are actual physical port numbers. Please see attached image regarding this.
