2017-12-28_06:04:41.82449 2017-12-28 08:04:41,824 ERROR: org.graylog2.gelfclient.transport.GelfTcpTransport - Connection failed: test
graylog 2.2.3
what does it mean?
reset the server solved the problem
The message simply tells you that Graylog (or more precisely the GELF client used by Graylog) wasn’t able to connect to the configured target host.
the problem was in graylog or in the remote host?
The TCP connection to the remote host.
