Hello, somebody know what is the meaning of this error???
I'm trying send logs to Graylog with a different IP to my APP. This is my configuration:

Define the graylog2 destination

log4j.appender.graylog2=org.graylog2.log.GelfAppender
log4j.appender.graylog2.graylogHost=tcp:192.168.254.184
log4j.appender.graylog2.graylogPort=12201
#log4j.appender.graylog2.originHost=192.168.250.96
log4j.appender.graylog2.facility=gelf-jsf-ui
log4j.appender.graylog2.layout=org.apache.log4j.PatternLayout
log4j.appender.graylog2.extractStacktrace=true
log4j.appender.graylog2.addExtendedInformation=true
log4j.appender.graylog2.additionalFields={'environment': 'DEV', 'application': 'GEOPromotions-Console'}

Send all INFO logs to graylog2

log4j.rootLogger=INFO, graylog2
log4j.category.uy.com.geocom.geopromotion.jsf.ui.view.UsersViewBean=INFO, graylog2
log4j.category.uy.com.geocom.geopromotion.jsf.ui.view.RolesViewBean=INFO, graylog2

Please help me
