Hello there,
I have successfully setup graylog unsecured in a docker environment and decided to go secured and make the switch to https. Unfortunately, I’m having trouble getting Graylog to talk to Elasticsearch. According to the logs everything comes up but it can’t find my Elasticsearch container and keeps trying to connect and times out. This results in a 502 on my NGINX proxy as it can’t connect. Hopefully someone can tell me what I have setup incorrectly. Here are the logs and details of my setup.
Below is the offensive log indicating it can’t connect to Elasticsearch.

Some background about my environment: I run 4 containers via docker-compose version 1.8.0, build f3628c7. Other versions are listed below. As you can see, docker is showing unhealthy because it can’t talk to Elasticsearch.

# 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
