Cannot Connect Pro Camera(s) to Wifi Mesh

[bdc12]

I recently moved.  I have an Eero Pro 6 mesh system and operated three Arlo Pro 4 cameras perfectly.  I moved the mesh wifi system but left the cameras, as I had a second set of three Arlo Pro 4 camera.

Yesterday I installed an Arlo gen 2 video doorbell flawlessly along with two remote chimes.  Today, I tried to install one of the Arlo Pro 4 and also a Arlo Pro 5S 2k, which I had purchased.  Neither will connect.  Both give audible chimes and then the blinking blue light goes out after a few seconds. I have followed every recommendation I could find online, including the following with no luck.  Any ideas or help would be helpful.

I have tried:

1. Removing all beacons and other eero systems, other than internet gateway

2. Reduced connectivity to 2.4ghz

3. Set up guest network with different naming and password (simple ones)

4. Tried legacy mode on eero

5. Removed all security features, also tried with each security feature enabled

6. Turned off client steering

7.  Verified no VPNs are running

8. Verified correct wifi username/password

9. Tried pressing sync button to keep blue light blinking when it times out after chime

10. Factory reset the Arlo Cameras something like 15 times each

I'm sure I am forgetting something else I have done, but given it is a new house, we have installed items from over 15 different manufacturers ranging from electric car charging, washer/dryers, TVs, water systems, computers, printers, etc, etc and never once have had an issue.  Any other thoughts of what I may be missing would be appreciated.  Otherwise, I presume I will just dump the Arlo systems and go with another vendor.

Are you utilizing WPA2? Can you try onboarding them over the web portal if possible?
