DVR ip address is not seen on PC

[bbqbrisket 0]

I can no longer log in to my DVR on my PC or other device.

I can access it directly at the DVR.

I Can also see video/cameras on devices (meye) but cannot gain access directly with DVR ip address for changes on either PC or other device.

I thought it might be the router but I cannot connect with ip address direct with ethernet, so

router seems to be OK.

Note: DVR is unbranded with no serial numbers.

 

any help is appreciated.
