@GiangiLuka

did you have issues connecting to IPv4 on this Graylog installation?

If you like to set the value to your startup variables you can find the default file location in the documentation ( http://docs.graylog.org/en/2.3/pages/configuration/file_location.html ) depending on your setup.

Jan

Hej @GiangiLuka

you need to modify the file that contains the JVM settings ( http://docs.graylog.org/en/2.3/pages/configuration/file_location.html#graylog ) and add the setting to GRAYLOG_SERVER_JAVA_OPTS.
