log stash issue

[aviv2]

hi guys, i have installed logstash on my ubuntu 64 bit server and nxlog, i have followed this guides

https://www.digitalocean.com/community/tutorials/how-to-use-logstash-and-kibana-to-centralize-and-visualize-logs-on-ubuntu-14-04

https://www.loggly.com/docs/logging-from-windows/

everythings works fine till it has lost connection.

it doesn't listen to the logstash port(5000) as i have configured and my nxlog port(6000) is listening on 127.0.0.1.

Foreign Address State

tcp6 0 0 :::22 :::* LISTEN
tcp6 0 0 ::1:953 :::* LISTEN


this is my logstash 01-lumberjack-input.conf file

input {
lumberjack {
port => 5000
type => "logs"
ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
}
}


and this is my nxlog config


<Extension _syslog>
Module xm_syslog
</Extension>

<Input in1>
Module im_udp
Port 514
Exec parse_syslog_bsd();
</Input>

<Input in2>
Module im_tcp
Port 6000
</Input>

<Output fileout1>
Module om_file
File "/var/log/nxlog/logmsg.txt"
Exec if $Message =~ /error/ $SeverityValue = syslog_severity_value("$
Exec to_syslog_bsd();
</Output>


i have tried to remove logstash to reinstall without succeed.
