Hi,

Configuring the network router or gateway to use Google public DNS servers can resolve connectivity issues cause by domain name resolution failures.

It is an SNS error, Here is the Procedure to assign Google DNS:

  1. Log into your network router as the Admin user.
  2. Locate the IP Address, Networking or DNS Server settings of the router
  3. Add one or both of Google public DNS Servers to the routers configuration
  4. EXAMPLE:
Primary DNS Server 8.8.8.8
Secondary DNS Server 8.8.4.4
Alternate DNS Server local router or ISP provided
  1. Save the Changes on the router
  2. Reboot the My Cloud
  3. Reboot the computer
