Outdoor Camera Not Working and Will Not Reconnect

Purchased 4x outdoor cameras in November 2023. On 16/02/2024 one of the outdoor cameras stopped working. I am unable to reconnect it. I have removed the device but when I try to ‘Add a device’ I follow the prompts and it says, “Is the blue light flashing” It’s a solid blue light, it states to “Ensure that you are pushing the setup button firmly and then releasing” which I have done several times but it still remains a solid blue light. Can any one help? Is this still covered under warranty?
