Server IP address could not be found, after Droplet upgrade
I upgraded my droplet (take snapshot, create droplet from snapshot, delete old droplet). All is success.
I notice that when I create new droplet from snapshot a New IP is served, so I manage my domain to point to the new IP of Droplet.
But now when I visit my site it says:
This site can’t be reached
www.domain.com’s server IP address could not be found.
My DNS is ns1.digitalocean.com, ns2, ns3....
Can you please help?
