Logstash configuration issue in VPN server

[inandi (Gobinda Nandi)]

I have a project in (A.B.C.D server). it is fetching data from third-party API. Now I want to store this data to my ES which is on a different server(P.L.M.N server). ELK server is connected with VPN ( openVPN ) and its IP address W.X.Y.Z . Now I am creating logtsash json file on my server. but failed to create the with json file with logstash conf file which is in VPN.

in my localhost, I can do everything but need help with this. unable to write the proper conf file I guess.

My logstash conf file sample

input {
	file {
		path => "/etc/logstash/review_data.json"
		start_position => "beginning"
		sincedb_path => "/dev/null"
		codec => "json"        
	}
}

filter {
	json {
		source  => "message"
	} 
}

output {
	#stdout { codec => rubydebug }
	elasticsearch {
		hosts => ["http://P.L.M.N:9200/"] 
		index => "data_student"
		document_id => "%{id}"
		template =>"/etc/logstash/review_template.json"
		template_name=>"tem_student"
		template_overwrite => true
	}
}

thanks @inandi

I have installed Logstash on my project server and I can connect my project to ELK and send-receive data. The problem is with VPN only. So I think this problem is no more related to this forum. Still, if u get anything before it gets closed please feel free to post any suggestions.

Thanks @inandi
