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 "*". -- cups 400 Bad Request for fully qualified host name https://bugs.launchpad.net/bugs/516018 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
