Invalid authentication data

[pa-t]

I have a c425 camera running firmware 1.3.5. I have been connecting to it with pytapo==3.3.19 via

tapo_camera = Tapo(host=CAMERA_ONE_IP, user=CAMERA_ONE_USERNAME, password=CAMERA_ONE_PASSWORD)

and up until today have not had any issues. I switched wifi networks today for the camera and had to reset the camera, now I cannot connect to the camera. I am getting this stack trace

Exception: Invalid authentication data

Looking for any guidance here on what could be wrong. As far as i can tell in my debugging is that there is an issue with the nonce here

if self.validateDeviceConfirm(
    nonce, responseData["result"]["data"]["device_confirm"]
)

@JurajNyiri that is odd though, I am fairly certain that it worked before on the same firmware. Is the only way forward to downgrade? Any plans to get this working on newer firmware versions?

Also I am on 1.3.5, not 1.3.8 or higher
