Ring chime second generation

Hy, I have an issue and I looked everywhere but couldn’t find any results. I have an 2nd generation ring chime , for two months worked absolutely fine, but now it doesn’t work anymore. On the ring app results OFFLINE. When I plug it into the socket, il flashes only once ( a blue light for one second) and that’s it. It tried to reset it, with no luck. I removed it from the app, and I tried to connect it again. But now the app can’t find it anymore. Did anyone had this kind of issue? If yes, could you please help me with some guides? Thank you!
