App can't locate new cameras after reading QR code when adding to current system. Others work well.

I installed 3 essential indoor wired cameras and the wired doorbell over a month ago and they have worked perfectly. Yesterday I tried to add 3 more cameras to the system but App can't find the cameras after they take the picture of the QR App code. I tried this several times with each camera and it just will not work. I even brought the cameras next to the Verizon Vios router but it didn't help. The original cameras and the doorbell all worked perfectly while I was doing this. I confirmed I was logged into the Wifi on my Apple phone and the signal looked to be full power. Because this is happening with all 3 new cameras its obviously not the cameras but the system. Not sure if I have to upgraded the subscription or what could be causing this problem.
