Solid yellow light v2

I have two Wyze camera, V2 cameras. They were both working fine and then all of a sudden they weren’t. After trying everything troubleshooting had listed I remove the app from my phone and deleted the cameras from the app as well. Now I re-downloaded the app I purchased the Kim plus program one of my cameras is working fine, but the other one will not get into set up mode. It is a solid yellow light. It will not flash. I’ve tried everything. Please help. In the other chat, it said that they had to authenticate some thing and it looked like you had the option to click on a hyperlink, but now when I click on the hyperlink it says error 404 message
