Seems I found the culprit. I use an SSL cert for the web interface and use mod-rewrite to redirect all traffic to https://
This apparently is not something FOG’s web service can handle so I modified my rule set as follows:
RewriteEngine on RewriteCond %{SERVER_PORT} ^80$ RewriteCond %{REQUEST_URI} !^/fog/service [NC] RewriteRule ^(.*)$ [url]https://%{SERVER_NAME}$1[/url] [L,R] RewriteLog "/var/log/apache2/rewrite.log" RewriteLogLevel 2For anyone else that wants to run their FOG web interface with SSL, I hope this helps. I’ll post anything else related to this if it comes up.
