You have setup FB for Logstash instead of Elasticsearch.
You should set:
output.elasticsearch:
# Array of hosts to connect to.
hosts: ["192.168.0.66:9200"]
#protocol: "https" # check this on ES side, most likely you are using https with username and pass,
#username: "elastic"
#password: "changeme"
# Performance preset - one of "balanced", "throughput", "scale",
# "latency", or "custom".
preset: balanced
# comment:
# output.logstash:
# The Logstash hosts
# hosts: ["192.168.0.66:5044"]
