Hello Jose.
We add website to aaPanel, it's Wordpress CMS (migration from A to B hosting). And after that import SQL and files, change IP configuration file too of course. And we add new IP to hosts, try to look website but get this error:
ERR_ADDRESS_UNREACHABLE
We get ping from URL name (it's interesting), but when try open website (after adding IP for domain in /hosts file) website doesn't opening.
