Spotlight Camera not connecting

One of our spotlight cameras has stopped connecting to the chime pro it was connected to. When resetting connection the chime pro can find it but can't set it up. All the rest are working fine so I know its not the internet connection. This has happened a couple of times in the last few weeks but after a few hours it suddenly connected again but this time nothing seems to work. It's still detecting movement and turning the light on but it's not connecting so can't see anything and its not recording. It is the blue light flashing after trying to set up which it says is internet connection but I have proved there is nothing wrong with the internet connection and the chime pro can connect to the internet fine. Any suggestions?
