This is likely a permission problem. On the master branch and while
using systemd, the servers are started running as the pdns user, and
not as root anymore.  So make sure the config file(s) are readable by
the pdns use. Ownership root:pdns and permissions 640 is likely a good
choice. And note https://github.com/PowerDNS/pdns/pull/8329 and
https://github.com/PowerDNS/pdns/pull/8330
