Note if you have upstream "example.net" defined elsewhere, nginx
will use it, and dynamic DNS resolution will not be used. Note
well that upstream may be defined either explicitly, using

upstream example.net {
...
}

or implicitly, using a proxy_pass to the given name:

proxy_pass http://example.net;

The latter sometimes confuses people trying to use proxy_pass with
variables to trigger dynamic DNS resolution of upstream names.
