Thanks for pointing me into the right direction. I can remember having
problems with Apache and mod_ssl in the past as they lacked of entropy with
no keyboard and mouse being attached to the machine. I have just installed
rng-tools and hope that this might solve the issues.
I'll report on it as soon as I can confirm that this was the cause.
