So what has caused the error?

In a little detail, "Error Code 17" often means the IP address of your CCTV devices (IP Camera, DVR, NVR) can't be resolved correctly, for whatever possible reasons. We have provided a premium DDNS service which is used to capture your home router's real-time IP address. If there is any issue (e.g router issue, ISP's service failure, etc) disrupting the communication between the DDNS resolving and the IP refreshing from your router,  you will see this error code 17.

To solve this problem, you need to instruct your CCTV system to resend your current IP address. Usually what you need to do is to restart your CCTV Camera DVR / NVR / IP Camera (shutdown / turn the power off, and turn it back on). The CCTV system will refresh your IP address, which should usually resolve the issue.
