The mimetype needs to be added to template for website vhost.

Thanks @arrfab for insight.

Commit d5fb0ae4 fixes this issue

I'm still seeing this behavior. As I understand the fix, it should have taken effect as soon as the playbook was run.

Ah whoops. That last commit was setting it for fedoraproject.org, but the fmw download is off getfedora.org.

New PR/freeze break: https://pagure.io/fedora-infra/ansible/pull-request/247

fedora-infra/ansible#247 has been approved and merged so this issue should be fixed (for good this time!).

Let us know if that's not the case :]

Assuming the playbook ran and httpd reloaded, it looks like it's still not fixed. :-( Still getting the browser's best attempt at rendering the dmg.

The proxy playbook is still running. It takes a long time.... because some of the proxies are very far away network wise.

I'll test it after it finishes.

ok, now it's finished.

It seems working to me, please test?
