[celine]

Hi,

I’ve this issue:

2020-10-12T22:58:59.480+02:00 WARN  [ProxiedResource] Unable to call http://IP:9000/api/system on node <34ad....70af3>: Read timed out

If I try with curl:

#  curl -i "http://IP:9000/api/?pretty=true"
HTTP/1.1 200 OK

  "cluster_id" : "5c7a43f............c41dc",
  "node_id" : "34ad0......70af3",
  "version" : "3.3.4+279ef2c",
  "tagline" : "Manage your logs in the dark and have lasers going and make it look like you're from space!" 

I doesn’t use any proxy. My configuration is:

is_master = false
node_id_file = /etc/graylog/server/node-id
password_secret = ***********************************

root_email = "***********************************@***********************************.com"

mongodb_max_connections = 1000
mongodb_threads_allowed_to_block_multiplier = 5
transport_email_enabled = false
proxied_requests_thread_pool_size = 32 

The sysconfig/graylog-server file is:

 # Path to the java executable.
JAVA=/usr/bin/java

# Default Java options for heap and garbage collection.
GRAYLOG_SERVER_JAVA_OPTS="-Xms12g -Xmx12g -XX:NewRatio=1 -server -XX:+ResizeTLAB -XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:+CMSClassUnloadingEnabled -XX:-OmitStackTraceInFastThrow"

# Pass some extra args to graylog-server. (i.e. "-d" to enable debug mode)
GRAYLOG_SERVER_ARGS=""

# Program that will be used to wrap the graylog-server command. Useful to
# support programs like authbind.
GRAYLOG_COMMAND_WRAPPER=""

Someone have an idea ?

Thanks !
