Upon disabling the default Apache site and reloading Apache + Nginx, I

requests to my WSGI application (CKAN). It would appear that CKAN is not
actually running. I understand this problem has more to do with Apache +
Nginx + WSGI and less to do with Vagrant + Ansible, but I'm including the
relevant portions in this email. I was under the impression that serving
the site with paster is not best practice, so there is something here I'm
missing. Any help would be greatly appreciated!
My understanding is that wsgi executes within apache.
I don't believe there is a separate process.
That being the case a look st the apache and nginx logs is probably worth a
look.
Hopefully it will identify both which piece of software is returning the
404 and possibly some further hints as to why.
More concrete suggestion is the name opendata.chattlibrary.dev set up in
the hosts file or end of the vm.
