Here is my server.conf file, I would post the entire thing, but evidently it exceeds the body character limit for posting:
############################
# GRAYLOG CONFIGURATION FILE
############################
# This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
# Characters that cannot be directly represented in this encoding can be written using Unicode escapes
# as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
# For example, \u002c.
#
# * Entries are generally expected to be a single line of the form, one of the following:
#
# propertyName=propertyValue
# propertyName:propertyValue
#
# * White space that appears between the property name and property value is ignored,
# so the following are equivalent:
#
# name=Stephen
# name = Stephen
#
# * White space at the beginning of the line is also ignored.
#
# * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
#
# * The property value is generally terminated by the end of the line. White space following the
# property value is not ignored, and is treated as part of the property value.
#
# * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
# For example:
#
# targetCities=\
# Detroit,\
# Chicago,\
# Los Angeles
#
# This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
#
# * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
#
# * The backslash character must be escaped as a double backslash. For example:
#
# path=c:\\docs\\doc1
#

# instances as master. The master will perform some periodical tasks that non-masters won't perform.

# This configuration setting has to be used if this Graylog node is available on another network interface than $http_bind_address,
# for example if the machine has multiple network interfaces or is behind a NAT gateway.

# and it will be used to generate URLs addressing entities in the Graylog REST API (see $http_bind_address).
