各位朋友大家好:   進行配置「Filebeat」證書加密 出現錯誤如下，有哪位朋友遇過此問題可以幫幫忙!   ERR Failed to publish events caused by: read tcp 192.168.1.57:56182->192.168.1.249:5043: wsarecv: An existing connection was forcibly closed by the remote host.   使用過「telnet IP Port」測試「ELK」服務器，確認通訊協議 OK !   Filebeat 配置如檔如下:  (Windows 環境)

filebeat.prospectors:
- input_type: log                      #輸入 type「log」
  paths:
    - D:\Wireshark_Log\*               #指定推送日誌「Log」文件
    
output.logstash:
  hosts: ["192.168.1.249:5043"]         #指定接收Logstash
  tls:
      certificate_authorities:
      - C:\filebeat-5.5.0-windows-x86_64\ssl\logstash\192.168.1.249.crt

      ssl.certificate:

 2017.09.08 感謝 medcl 兄弟幫忙，再次修改如下:

filebeat.prospectors:
- input_type: log                      #輸入 type「log」
  paths:
    - D:\Wireshark_Log\*               #指定推送日誌「Log」文件
    
output.logstash:
  hosts: ["192.168.1.249:5043"]         #指定接收Logstash
  ssl:     # <=== 新版本貌似要改成「SSL」
      certificate_authorities:
      - C:\filebeat-5.5.0-windows-x86_64\ssl\logstash\192.168.1.249.crt

      - C:\filebeat-5.5.0-windows-x86_64\ssl\filebeat\192.168.1.57.crt
      ssl.key: # <===  修正為「ssl.key」      
      - C:\filebeat-5.5.0-windows-x86_64\ssl\filebeat\192.168.1.57.key

意思是說  证书对 192.168.1.57 有效，而不是192.168.1.249 。 這裡有些不明白...
