Since a few days ago, we're having issues with resolution of this hostname:

Our FreeIPA DNS servers return SERVFAIL for that particular hostname. What's funny, after I do a (successful) lookup directly at one of the configured forwarders, 1.1.1.1, resolution works, until the TTL expires. Other hostnames work fine. How can I troubleshoot this? 

FreeIPA versions:

ipa-server-4.6.5-11.el7.centos.4.x86_64
ipa-server-dns-4.6.5-11.el7.centos.4.noarch
