I’m trying to use the EFF certbot to generate and configure the certificate on my webserver.
I’m using the simple command: certbot --apache.
The authorization procedure is failing with the error:
Failed authorization procedure. security.claudio.pt (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: DNS problem: SERVFAIL looking up CAA for security.claudio.pt
Using dig security.claudio.pt @18.104.22.168 -t type257 I can confirm that the status is indeed SERVFAIL.
I actually never heard of this record. The only way to solve this is to ask the register to add this record to the my dns zone ? Is there a option to bypass this error?
If it is, is the following record correct?
