First you need to set a static IP address in the NVR network settings.

Password = whatever your NVR admin password is Port = leave at 8000 unless it has been changed - assume it hasn't Address = the IP address you noted earlier Alias = Home - WiFi (or anything you like)

Click plus in the top right & select manual adding You'll find that in the network settings menu - make a note of it.
To do that first find out what the internal IP address of your NVR is. The first thing I'd do just to prove that it's an issue with connection to Hik Connect is to try connecting directly to your system while on your WiFi. When that happens there are issues connecting via the Hik Connect service. It can and usually does work that way but from time to time something goes astray - the internal IP address changes or UPnP doesn't work as well as it should. My guess is that if you go into the settings of the NVR you will find that the IP address has been set up for DHCP (IP assigned by router) and that it's also setup to use UPnP (automatic port forwarding). I have a standard way of setting the systems up for remote access and I find that it's often easier to set it up right first time, than it is to fix it. It's difficult to pinpoint what's not right as it depends how your installer (or you) setup the connection to the system.
