title: Guacamole error: Remote Desktop server is currently unreachable
body: <p>I have setup a Guacamole server on Ubuntu 16.04 with Tomcat7. Everything was working great. I added a second database for a side script that i'm running. Went to log back into my Guac server and I can still reach the login page, but once I try to login I get the error message: Remote desktop server is currently unreachable, trying again in 15 seconds. I am never able to reach the Guac web application (aside from the login screen).</p>
  
  <p>/var/log/syslog shows me this: (not very helpful)</p>

  <p>Things I have tried:</p>
  
  <ul>
  <li>Added guacd-hostname and guacd-port to guacamole.properties file</li>
  <li>Rebooted the system</li>
  <li>Restarted Guacd service</li>
  <li>Tried to change logging to "debug" with a logback.xml file but that didn't seem to change anything, or I don't know where I'm looking</li>
  </ul>
  
  <p>Things that might have caused this:
  - I created a new ubuntu user and setup a web root folder under their home dir
  - Changed owner of this /home/~username/public_html folder to the apache user "www-data" (this might have affected other folders?)
  - Installed phpMyAdmin</p>
  
  <p>This is running in AWS. No security groups or IPs have changed since it was working.</p>
