It’s an SNS error; follow these steps to assign Google DNS:
As the Admin user, log into your network router.
Lookup the router’s IP address, networking settings, or DNS server information.
Change the router’s configuration to include one or both of Google’s public DNS servers.
EXAMPLE:
DNS Servers: Primary 8.8.8.8 Secondary 8.8.4.4
A different DNS server is offered by the local router or ISP.
the router’s changes by saving them
