I have in the same machine Elasticsearh, Logstash and Beat/filebeat.
Filebeat is configured to send information to localhost:5043.
Logstash has a pipe configuration listening on port 5043.
If I ran netstat -tuplen I see:
[root@elk bin]# netstat -tuplen | grep 5043
tcp6 0 0 :::5043 :::* LISTEN 994 147016 31435/java
Which means logstash loaded the pipe and is listening on the expected port.
If I telnet to localhost and port 5043:
[root@elk bin]# telnet localhost 5043
Trying ::1...
Connected to localhost.
Escape character is '^]'.
^CConnection closed by foreign host.
[root@elk bin]#
Which means the port is open.
However when I read the filebeat's log, I see:

I am missing a elephant in the room? Why is the connection "reset by peer"?

###################### Filebeat Configuration Example #########################
# This file is an example configuration file highlighting only the most common
# options. The filebeat.full.yml file from the same directory contains all the
# supported options with more comments. You can use it as a reference.
#
# You can find the full configuration reference here:
# https://www.elastic.co/guide/en/beats/filebeat/index.html
#=========================== Filebeat prospectors =============================
filebeat.prospectors:
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
- input_type: log
# Paths that should be crawled and fetched. Glob based paths.
paths:
- /tmp/*.log
#- c:\programdata\elasticsearch\logs\*
# Exclude lines. A list of regular expressions to match. It drops the lines that are
# matching any regular expression from the list.
#exclude_lines: ["^DBG"]
# Include lines. A list of regular expressions to match. It exports the lines that are
# matching any regular expression from the list.
#include_lines: ["^ERR", "^WARN"]
# Exclude files. A list of regular expressions to match. Filebeat drops the files that
# are matching any regular expression from the list. By default, no files are dropped.
#exclude_files: [".gz$"]
# Optional additional fields. These field can be freely picked
# to add additional information to the crawled log files for filtering
#fields:
# level: debug
# review: 1
### Multiline options
# Mutiline can be used for log messages spanning multiple lines. This is common
# for Java Stack Traces or C-Line Continuation
# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#multiline.pattern: ^\[
# Defines if the pattern set under pattern should be negated or not. Default is false.
#multiline.negate: false
# Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
# that was (not) matched before or after or as long as a pattern is not matched based on negate.
# Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
#multiline.match: after
#================================ General =====================================
