Arlo Pro 3 Hub - cannot find an Arlo device

[RSouth]

I have tried to setup my Arlo Pro 3 Hub and it keeps telling me it cannot find an Arlo device.  I have called Arlo support and they tell me that I need to open closed ports on my router.  Has anyone had to do this?

RSouth,

What is the LED behavior on the SmartHub?

For information on LED behavior: What do the LEDs on my Arlo SmartHub or base station mean?

For information on minimum requirements, take a look here: What are the minimum requirements for installing and using my Arlo system?
