Outdoor Camera refusing to connect to WiFi

​The camera worked as usual before today. The camera had minor issues mainly due to the cold but now it's just frustrating. It refuses to show the live feed even after replacing the battery with a completely new one I bought not too long ago. Now I've removed the camera from my system and now it refuses to connect to my wifi. The system recognizes the camera but it just won't connect to the wifi anymore. Everything else with the system is fine including the indoor camera (just fyi).​
