Outdoor Camera won’t reset or re-connect

My outdoor camera battery drained, even though it was hooked up to solar. After fully recharging the battery, it would not reconnect. I removed the camera and tried to add it back, but instead of chiming and blinking white it goes right to flashing a blue light and would not connect with the base station. Holding the back button does not result in a reset. The light simply stays flashing blue. How else can I reset this thing?
