title: Pritunl setup with Amazon Documentdb
body: <p>I'm setting up pritunl and I want to use Amazon Document DB instead Mongo DB or Mongo DB Atlas. This is for a vpn idea that I had, server is running ubuntu 18.04 and followed the standard install guide from pritunl, I have it working correctly with MongoDB but for DR and scaling purposes I owuld like to get this into the AWS Document DB.</p>
  
  <p>I have modified the /etc/pritunl.conf file and replaced the default local mongodb_uri with the document DR URI. restarted the service and I would exspect to see the pritunl login/setup page there.  I have opened the retired ports on the box and run thought the pritunl setup page and it just hangs</p>
