When setting up the Hikvision DDNS for remote access to your camera system, you may encounter the error “Communication to Server Failed”. This error is caused by the DNS settings (note: DNS, but not DDNS) in your NVR/Camera configuration. This guide will give you the step-by-step instructions to resolve this error and save your DDNS settings successfully.
Connect the NVR to the internet via a network cable.
Connect a mouse and a monitor to the NVR.
Log into the menu and select the configuration option
Click on Network and then General tab
In the Preferred DNS field enter 220.127.116.11 and in the alternative DNS field enter 18.104.22.168 and click apply. These are Google’s DNS servers.
You may need to restart the NVR for the above settings to apply successfully.
Click the DDNS tab
Once applied you should now be able to save the DDNS settings successfully without any errors.
