Dorrbell not charging wired and doorbell not ringing

Hello, so my ring doorbell is no longer charging, i have it hardwired and it was working great but all of the sudden it stopped charging. I checked my breaker and power to the doorbell and its fine. The only way i can charge it is by removing it form the wall and charging it with a cable. I am also having a problem with my doorbell not the actual ring but my doorbell in my home that rings when the button is pressed isnt going off. I thought that it may be broken but when i bridge the two screws on the ring mount it rings. Is this a problem with the mount or the actual doorbell and if so what can i do to fix it? -Thanks
