Foreman can’t import Puppet Environments

I'm running Foreman 1.7 with puppet 3.4.3. I've configured my environments using this: http://projects.theforeman.org/projects/foreman/wiki/Troubleshooting#Smart-proxy-do-not-recognize-my-puppet-environment

Of course the default "Production" environment shows, but when clicking "Import from Puppet" it just shows the green box "No changes to your environments detected". $confdir/environments/staging/manifests/site.pp exists, but it didn't seem to be required for Production to show up.

Smart-proxy log shows this:

10.210.102.3 - - [16/Dec/2014 18:06:25] "GET /puppet/environments HTTP/1.1" 200 24 0.0240
10.210.102.3 - - [16/Dec/2014 18:06:25] "GET /puppet/environments/production/classes HTTP/1.1" 200 2 0.0879
10.210.102.3 - - [16/Dec/2014 18:06:25] "GET /puppet/environments/staging/classes HTTP/1.1" 200 2 0.0861

So it's able to find the staging environment.

Any ideas?
