Chime 2nd Gen Won't Connect to WiFi

Hi All, I seem to be having an issue with my Chime. I bought it last November and it has been working well for a good 6 months. A few weeks back I noticed that it was not ringing but didn't get around to it straight away. Over the past few days I've been trying to get it working and it does not want to connect ot my account. On my account there seems to be no Chime devices attached. I've attempted to connect my Chime via my Android Phone as well as my iPad Pro with no luck. I've tried connecting it to my Home WiFi (Virgin Media), a guest WiFi on my router as well as my phones WiFi hotspot. All fail the same way. When connecting the Flashing Green light turns to a flashing Blue light. Then after around 45-60 seconds it turns to a flashing Red then I get an error on my device saying there was an error and then I get nothing :frowning: Is this something people have seen before and are there any fixes known? Thanks Thomas
