NVR freezing (sometimes) Question?

[TonyR]

If the NVR is non-POE and you have a POE switch running POE camera video through the router to get to the NVR LAN (also on router), that very well could be your bottleneck.
Instead, run NVR LAN to POE switch.

UPDATE:
I have three cameras disconnected to dry out the moisture.
these are disconnected:
2) of the IPC-HFW5241E-Z12E
1) IPC-T3241T-ZA
MY NVR just froze again.
NVR is a POE

Still trying to troubleshoot it.

Yes, I see live and can play back the recordings.

I have the

ASUS ROG Rapture GT-AX11000 Pro Tri-Band WiFi 6​

and two

D-Link 10-Port Gigabit Smart Managed PoE+ Switch | 8 PoE+ Ports​

Everything works fine.
It occasionally freezes. and I do not know why?

Thanks
Sam

Just to get an idea of your network topology, the router is connected to one of the 10-port switches and the cameras and NVR connected to the same switch or are the cameras and NVR on the second switch and connected to the first switch in a daisy-chain?
