Ring Indoor Cam not connecting to wi-fi during setup

Hi all I have an indoor cam that is playing up and dropped off my home wi-fi. I have attempted to re-connect it. The app sees the correct wireless network and tries to connect the cam to it but eventually it tells me that there was an issue and the cam light flashes red and blue. I have tried completely resetting the cam and setting it up from scratch but same result. I have another indoor cam and thought possibly it was my wi-fi or firewall but I've completely reset it and it sets up fine with no issues at all from the same location as the faulty cam. I think maybe there is something more going on with this cam and it may be faulty. Anyone come across this issue before? Any ideas for a fix? Thanks
