Hello, Since a few days ago, we're having issues with resolution of this hostname:
download.wisselkoersenvoorjeadministratie.nl 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?
