<p class="MsoNormal">Hi Sami.<o:p></o:p></p>

<p class="MsoNormal">In the "response-policy" block in your config, what (if anything) is the value of the statement "qname-wait-recurse"?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">If you do not have that set explicitly, please do "named -C" to list the defaults and see what it is; probably "yes".<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This parameter controls whether RPZ waits until successful recursion has finished before it rewrites the response, according to the matching rule in the RPZ zone.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">If there is no successful response from recursion then RPZ has nothing to rewrite, so your server's response to its client will be SERVFAIL.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">It looks like your server cannot resolve cadyst.com/A for some reason, which would explain what gets sent back to the client.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">However, it resolves fine for me:<o:p></o:p></p>

Upgrade to 9.18, because 9.16 does not support extended DNS errors.<br>
<br>
See<br>
<br>
<a href="https://gitlab.isc.org/isc-projects/bind9/-/issues/?sort=created_date&state=all&label_name%5B%5D=Extended%20DNS%20Errors&first_page_size=20" target="_blank">https://gitlab.isc.org/isc-projects/bind9/-/issues/?sort=created_date&state=all&label_name%5B%5D=Extended%20DNS%20Errors&first_page_size=20</a><br>
<br>
For which errors are supported.<br>
<br>
Best regards, Matthijs<br>
