Elasticsearch 集群故障后 Filebeat 无法发送日志

Question

We recently had a problem when ES cluster failed. The problem was resolved, but filebeat failed to send new data after the failure.
Here's a portion of the logs - it seems to retry forever but can't send the data:

2019-04-08T11:52:04.182+0300    INFO    elasticsearch/client.go:690    Connected to Elasticsearch version 6.4.0

I restarted Filebeat service and all data was sent to ES without any problem.
Is this a known issue? Filebeat version is quite old, should I update?
I'm running Filebeat 6.3.0 as a service on Windows. Elasticsearch version is 6.4.0.

Please show your profile
I have encountered this error before because I did not write the procotol
Below is a correct configuration file

filebeat.inputs:
- type: log
  enabled: true
  paths:
  - /var/log/dmesg
  - /var/log/syslog

output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["http://192.168.13.173:30014"]
