This is the default security setting used by the PDF server and does not represent an error. The IP address 10.128.11.67 is the addressable IP address of splunkweb (that requests PDF services).

Users may choose to disable this security check in pdf_server.conf via:

# Uncomment to allow the server to render web pages other than those served up by 
# an instance of Splunk
# restrict_to_splunkweb = False

Users may also expand the list of allowed IPs by changing the following key in pdf_server.conf:

# IP addresses of Splunk appservers (or other servers) that the pdf server is
# permitted to query - Deaults to any IP
# Both IPv4 and IPv6 network declarations are supported
# appserver_ipaddr = 192.168.4.0/24,192.168.3.0/24

As a security best practice, these settings should generally not be changed.
