Check whether the firewall is started and whether the port is open:
systemctl status firewalld firewall-cmd --list-all

aaPanel_Kern firewall-cmd --list-all

aaPanel_Kern ok this work but still cant access my domain..
and after i ping i see my ip domain has been changed how to solve this.. i see in dns seting domain in aapanel still same before i got error...

YagamiCell
Hello, it may be that the dns manager cannot propagate. It is recommended to use the domain name provider's management website directly.

YagamiCell

aaPanel_Kern u have the tutorial for this

aaPanel_Kern

NO tutorial

YagamiCell

aaPanel_Kern sorry for that but i dont understand with this "domain name provider's management website directly."

aaPanel_Kern

YagamiCell
The DNS manager of the panel does not propagate. Please directly use the domain name provider's management website to manage domain name resolution.

aaPanel_Kern ok my problem has solved after i wait a for one hours, maybe for propagate.. and now i can access domain again... thanks for ur help
