Hello,

I ran across this while having the same error. I'll add this info for
others to see...

It is best to use the "ServerAlias" directive with an actual hostname
versus the "*" command

Just add it to the end of the cupsd.conf file

Example: ServerAlias server-name.your-ip.com

Reason:    http://www.cups.org/documentation.php/ref-cupsd-conf.html

    Note

    The ServerAlias directive is used for HTTP Host header validation
when clients connect to the scheduler from external interfaces. Using
the special name "*" can expose your system to known browser-based DNS
rebinding attacks, even when accessing sites through a firewall. If the
auto-discovery of alternate names does not work, we recommend listing
each alternate name with a ServerAlias directive instead of using "*".
