Do you have any kind of CDN in play?
If you ssh to your server, and try
wget -q --timeout=3 https://localhost/privacy -O - |egrep generator
does that work?
How about
wget -q --no-check-certificate --timeout=3 https://localhost/privacy -O - |egrep generator
How about if you put your full URL in there instead of localhost? Try both versions of the command.
