Outdoor cam went off line; won't come back on line 1-20-2022

My outdoor cam went off line on Jan 20 2022 around 1 - 2 pm EST. I have unplugged it; charged it; turned on and off; Unplugged the base; plugged everything back in still off line; checked the software to make sure everything was up to day NOTHING.
What do I do now?

You have your battery powered cam plugged in to what? constant power, solar panel? You could always try to change the camera firmware back to a previous version. Does the base have a solid blue light on?. What does the LED light on the camera do when you turn the cam on, yellow, red, blue, flashing any of those colors?
