I can connect to my wordpress/ubuntu droplet through Putty and DigitalOcean console, but not through any web browser to connect to wordpress login admin. The problem: tcp ports 80 and 443 are now showing closed and connection refused. DNS A record (DO gave me a new IP) also not cached around the world even after 4 days. Double checked configuration in the droplet and set droplet firewall (even though none were set in the first place), and applied sudo rules UFW in console for allowing the ports. Domain is configured correctly. Disabled my own firewall on windows. What could the problem be??

EDIT: one possible answer to this is that when I went to rebuild the snapshot for this droplet I was given a new IP address. I am told that I should not have been given a new IP address. Presumably it has either created an entirely new droplet or is corrupted.
