Main stream when solo - Check FPS and key rates

All of my cameras that run on sub stream can't seem to display main stream when I solo the camera anymore. It used to work but sometime in the past few months it stopped and I'm not sure if it was an update or not. I'm on 5.9.9.98 but it happens on 5.9.9.73, too. All of my cameras are Empiretech - Dahua equivalents. The thing is, the main stream DOES work. When an event triggers, I can see the full quality mainstream in the video playback in Blue Iris. I have 2 cameras running on continuous main stream and those work fine. If I swap my sub stream cameras to continuous main stream only they fail to connect. When I click to solo the cameras, about the same amount of time it takes for main stream to normally toggle, a warning icon shows and when I check settings on the camera with the warning icon it says to Check FPS and key rates. If I toggle OFF "Main stream when solo/full screen" and then solo a camera, the warning doesn't occur. I can also see main stream as normal in the camera UI. Any ideas? I feel like I've monkeyed with so many settings in BI and camera UI and nothing. It definitely used to work, I just can't remember when it stopped - i solo the cameras when I'm near my pc and see someone walking up and always would see the quality switch within 1-2 seconds. That no longer occurs.

If I use one of the cameras, in BI it says this:
Check FPS and key rates
Main stream
3.7MP, 13.98/0.01 fps, 1050.0 kB/s
Sub stream
0.4MP, 12.06/1.00 fps, 102.1 kB/s

In the camera UI, the encode for main/sub stream is:

In my experience, when you get that message you are either using smart codec, h265, VBR, SSA, the power supply is failing, or there is a networ bottleneck.

Since those look right, I would look at Network and power.
 
All of my cameras are POE to the same switch. If the switch is failing would I see it on all the cameras? I don't see it on my 2 continuous cameras. Cameras are on h.264, CBR, SSA off (but some do have WDR backlight). And the main stream works, just not when I solo the camera for live view.
 
Nope you could have one port failing.

This is how I first noticed this phenomenon with BI that others have seen over the years as well.

Another thing you could try is delete the camera in BI and re-add by scratch in the event it corrupted in BI.

Tried other ports and swapped several around still same. Deleted camera and readded with .reg import and same... I'm going to buy another switch just in case it's the whole unit. If that doesn't work I may just live with it because triggered main stream works. It's really only a minor inconvenience for solo selection.
 
Ok I did it again but from scratch and even used different camera name and still the same. Maybe I just need to do the whole factory resetx3 chart and readd... etc
 
Wow... It's always the little stuff. I hit so many settings but the one that solved it was setting hardware decode from Default to No. Now it's working. I was assuming default was unchanged since it was working previously. Maybe one of the updates this year toggled it.
