The password for your camera's Wi-Fi is randomly assigned each time you pair. So after you unpair, you need to press the Exclamation mark from your iphone's Wi-Fi setting page and select Forget this Network. And then connect to the camera's Wi-Fi again, long-press on the box where you enter your password and select Paste. After the camera's Wi-Fi is connected, go back to the App, you should be able to see that you have successfully connected to your camera.
