After running Logstash, getting error "Missing kbn-version header" .

Please show your Logstash configuration (the logstash.conf file). And next time please don't post screenshots of console windows from which you can copy/paste plain text.

In logstash.conf, localhost port mentioned was wrong, on correcting it to 9200, started working.
