Topic: Create CAA DNS record that support any sub-domain
Here is my domain: dandelionsystem.myDNSSEC: enabledI created 2 CAA dns record as follow:Node: <blank>Type: CAATTL: 120Flags: 0Tag: issueValue: letsencrypt.orgNode: wwwType: CAATTL: 120Flags: 0Tag: issueValue: letsencrypt.orgat my web server, I am able to create Let's Encrypt SSL for the following:dandelionsystem.mywww.dandelionsystem.myhowever, when I try to create SSL for test2.dandelionsystem.myI received error message as follow:{"type":"urn:ietf:params:acme:error:dns","detail":"DNS problem: SERVFAIL looking up CAA for test2.dandelionsystem.my - the domain\u0027s nameservers may be malfunctioning","status":400,"instance":null}if I tried to create another CAA:Node: test2Type: CAATTL: 120Flags: 0Tag: issueValue: letsencrypt.orgthen it works, the SSL created successfully.My question is, how to set the CAA, so that I won't have to create new CAA for every new sub-domain?Is it able to create single CAA that allows Let's Encrypt SSL to install on new sub-domain (without creating additional CAA)?thanks.
