Arlo Pro 2 only 1 cam is working - Help opening ports

[elmotley]

Since I bought this cameras last November, Only 1 camera is connected/working. I have called ARLO many times,  we did all kind of resets and the last suggestion they gave me was to open more ports. They gave me 3  different digits to do it. Here's the problem, I took a note left it next to my computer and apparently was thrown at the trash. I no longer have that info. Can someone help me on this issue? Thank you so much!!!

They are port 80, 123 and 443 to arlo.com but unless you've made changes to the router or the ISP owns it and has blocked things, there's no need to do this.

Tell us in detail what the problem is, what you've tried and everything you see.
