Domain ssl certificate don't install and can’t be renewed

My sites:

provider.realize.pro.br don’t install SSL more than 48 hours ago

and

fieb.realize.pro.br don’t renew SSL certificate too

In install case (provider.realize.pro.br) the status: " Waiting on DNS propagation" never complete (more then 48 hours)

In renew case (i have this site for 3 year or more) get this error:

SniCertificate::CertificateNonvalidError: Unable to verify challenge for fieb.realize.pro.br: DNS problem: SERVFAIL looking up CAA for fieb.realize.pro.br - the domain’s nameservers may be malfunctioning
