Cameras frequently don't load on a layout (Three dots)

Summary

On my client, I frequently get cameras stuck on the "three dots" where some cameras will not load on the layout. For example, this morning three of the 36 cameras did not load until I closed the layout and reopened it. Generally, they will continue showing the three dots until the layout is closed and reopened, and the problem will not resolve itself. The cameras are recording to the server the entire time.

Environment

Nx Witness Version: Digital Watchdog Spectrum 5.1.0.37133
Client OS: Windows 11 Enterprise 22H2 build 22621.3155
Server OS: Windows 10 Enterprise 22H2 build 19045.3448
Network Topology: 4 DW Spectrum servers (Windows 10 Enterprise, 32GB RAM, Dual Intel Xeon Silver 4208 CPUs, 256GB SSD {OS}, 100TB video storage in JBOD configuration) / 146 Cameras with 180 licenses / 6 Fortinet layer 3 FPOE switches dedicated to the camera network, fiber backbone, none at capacity / 3 always on clients, 3 DW Spot 16 channel monitors / 32 users, any number of which can be viewing at any given time
Special features: None

Reproduction Scenario

Issue occurs immediately in the morning when client is launched via the following batch file:

@echo off
cd C:\Program Files\Digital Watchdog\DW Spectrum\Client\5.0.0.35746
applauncher --window-geometry=10,10,1900x1020 --layout-name="JPs Detention Layout" --no-single-application --auth=http://{user}:{password}@{IP}:7001
exit

Expected Behavior

When the layout loads, the cameras should all be visible with minimal load time.

Actual Behavior

When the layout loads, two to four cameras frequently do not load, instead show the following:

Additional Information

I'm not sure what will be helpful, but will provide whatever you request.

I have a similar issue with Witness. 5.1.1.37512. Within the same layout, 6 cameras from the same NX server. One camera pops up instantly, and the other 5 cameras take 30secs+ to show up.

Anyone has solution for this?
