unable to add floodlight cam to pathway light group

I have spoken to customer support without success. I try to add a floodlight cam to my pathlight group of lights. It repeatedly tells me to try again later. I have tried rebooting all hardware, uninstalling app, updating firware, and trying android and iphone versions. When i try to add the floodlight cam light to the group under the floordlight cam settings, it says http 500. Any help would be apprecited. thank you!
