I have 7 NVRs Hikvision. All are remote access. but now I check that 1 NVR does not access on IVMS-4200 client. and it gives an error like "receiving data from device timed out hcnetsdk.dll 10 error." kindly guide me about it. Remaining NVRs are showing cameras perfectly. but now I don't know what happen to this NVR. I also attach Screenshot hereunder.
