Hello community, We are experiencing a resolution problem: 'SERVFAIL error'. Our environment is BIND 9.16.48, OS: Redhat8. I am sharing with you a part of the log that contains this error, named.conf file.
What I've noticed is that the resolution problem is mainly related to domain names that contain a CNAME record in the response, such as 'account.api.here.com' and 'push-rtmp-l96.douyincdn.com' P.S. DNSSEC is temporarily disabled to facilitate the diagnosis of the issue. Regards Orange Restricted
