PowerDNS mysql backend error ubuntu 16.04

Hi!

I’m trying to install PowerDNS on a Ubuntu 16.04.3 VPS with a MySQL backend. But struggling with an error.

Installed following packages from apt:

• mysql-server
• pdns-server
• pdns-backend-mysql

When I’m doing dns lockup the server only respons SERVFAIL. In syslog I find: pdns[2144]: Exception building answer packet (stou) sending out servfail

Any ideas?

Thanks! Erik
