Hello,This image belongs to my main domain DNS information. 
This is information about a normal domain. I can access the main domain but I cannot access the ones I added later due to a DNS problem.
I could not configure DNS Manager
Hello, please use a domain name provider or third-party domain name management. It is known that some records of the DNS manager will not be disseminated.
aaPanel_Kern Is there a DNS software that you can recommend that I can add to the panel?
Hello, not available at the moment, we recommend you use CloudFlare
