This is rarely the case, but sometimes to run certain services on Linux let alone who need access online is still using the old DNS data. So if for example we change the domain or want to download the file that the server IP just changed.
Because I’m lazy to wait and indeed urgent urgent I finally find a solution, ie clean DNS cachenya that exist on the Linux server. 😀 It was easy.
CentOS (usually)
service nscd restart
Ubuntu
service dnsmasq restart
If it fails all ya have to edit the hosts file in Linux. 😀
