shahinsafari Hello 1- DNS port in Apnel Is it 53? 2- Which ports should I add in UDP and TCP mode in the firewall? Thank you for your good support
aaPanel_Kern Hello, dns is 53/udp by default At present, there are known problems with the dns manager. Some records will not be propagated. It is recommended to use the management website of the domain name provider. Or a third-party domain name management website.
shahinsafari aaPanel_Kern About the domain I can install another tool related to dns maneigr on my server so that there is no problem there is no difference For me in operating system usage between Ubuntu Cent OS and Debian Is this known problem that you said exists in all operating systems?
