To check the problem, the first step is to log on to your www.cameraftp.com account. Click the message icon on the top-right corner to go to the Event Center. You might be able to find some error messages there.
The second step is to verify if your camera was configured with the correct parameters. In My Cameras page, click the gear icon below your camera thumbnail.
If you don't see anything wrong in your account, then usually it is caused by the camera or the network. Please reboot your camera and/or router.
You mentioned that you changed the service plan from monthly to yearly. Usually you also need to change the FTP password in your camera settings. You can find the new FTP password in the "Configure IP cameras" page.
