No connection, battery not charging

I bought a ring stick up camera for outside last August. A few days ago it started saying it wasn’t connected to the internet and had no signal. It was charged (68%) and my internet was working ok. I completed the trouble shooting process but it still wouldn’t connect. I pressed the orange button to reboot but no blue lights flashed. I reset my internet and that made no difference. When I plugged the battery in to charge no orange light came on only a green one. The battery is not fully charged though as it hasn’t been charged for a month. I tried different a different plug/cable and the same thing happened. I deactivated the camera to try and re add it to see if that worked but it didn’t. Surely the camera shouldn’t stop working after just over a year? My ring doorbell one is working fine still so I know it’s not an issue with the internet here. Has anyone any advice please? Thanks
