Device or resource won't accept the connection

Device or resource is not set up to accept connection on HTTP.

I have 4 IP cameras connected to an Amcrest NVR, everything is working just fine.

However I cannot view the NVR in Internet Explorer.

I can view the cameras.

I can ping the NVR OK from my computer and using network test the NVR can ping my computer.

IE 11 Windows 8.1 Windows firewall off AV off. Linksys router with DD-WRT I have the IP address of the NVR enabled in DMZ.

The NVR's IP address is set to static 192.168.1.99

I did Google this but no luck, thanks
