Hello all. I have a Dahua NVR 4116-8P-4KS2/L with 3 PoE cameras for a month now. Everything works fine and it is also successfully connected to the internet. But I can not access the web interface. When I try to access it with the IP of the NVR, I can't get to the interface. The connection cannot be established. Do I need to enable the web interface somewhere or something?
I am very grateful for any answer!

Is the NVR's LAN IP (the one you open the browser to) and the LAN IP of the PC where the browser is being opened, on the same subnet ?

IOW, if the NVR's LAN is 192.168.1.XXX is the PC 's LAN IP also on 192.168.XXX subnet with a different and unique IP?

When you say " The connection cannot be established", what sort of message/popup is displayed?

Hi TonyR,
Thanks for your quick reply. I have linked you the photo of the error message.

The IP of the NVR is: 192.168.1.108
and that of the PC: 192.168.1.105

I hope I could clarify your question and I would be very happy to get an answer from you.


I am sorry the error message is in german. here is the translation:

The website is not accessible.

192.168.1.108 has refused the connection.

Try the following:
Check connection
Check proxy and firewall

Have you attached a dahua camera to the same net? If so, turn it off and try again. But I would assume your cams are all connected to the recorder?
 
That 192.168.1.108 IP address is pretty suspicious, being the default IP address for Dahua devices. As alluded to in the post above, one possible cause of your problem is more than one device on 192.168.1.108. Do you know how to check for that? One way is to pull the NVR off the network then ping 192.168.1.108 to see if there's a response.
 
Know this is an old thread, but I had the same issue today and decided to create an account here.

Turns out that when you connect an ONVIF camera to the NVR it changes the HTTP listening port from 80 to 8089. I assume this is because ONVIF uses port 80 typically, so does this to avoid potential conflicts.

You can find this by logging into the NVR - network - tcp/ip - ports.

So instead of typing eg: 192.168.1.10 into the web browser, you type 192.168.1.10:xxxx (x is the port number found in that section)

Hope this helps someone in future.

If you use a separate switch for the cams, it uses 37777, so if you click on Internet exploder (blue E) link it opens a browser page to the Ip's as shown below.

Did Your NVR address changed in the Port#? wow. Ive seen those port numbers do weird things when the cameras are directly plugged in to 4116 NVR.
my NVR IP stayed stable, but logging into the cameras web interface from inside NVR would I would see a 192.168.0.147:10808 or something. And it was painfully slow, as the Nvr had a 80Mbps thruput.
putting them on a gigbit switch alleviated all that.
