 From here, "user.test.com" resolves to 69.172.200.109.

So, are you actually trying to resolve "user.test.com"?  If not, then 
you need to tell us what the real domain is.  See: 
https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/

If it is a fully delegated domain in the public DNS, then we can check it.

If it is *not* a fully delegated domain in the public DNS, this means 
you must have other configuration which is relevant (e.g. a private 
authoritative server, and recursor configuration to forward to it).  
Therefore, show us that configuration.

Finally, try running dig without +short.  What status you see when there 
are no results - NXDOMAIN, NOERROR, SERVFAIL, REFUSED, something else?
