Logstash error "Missing kbn-version header"

I am new to ELK and have installed ES 2.1.1, Kibana 4.3.1, Logstash 2.1.1 on Windows.
After running Logstash, getting error "Missing kbn-version header" .
Attached snapshot of the error seen in logstash and also in kibana.

Not able to figure out what this version header means and how to resolve it.

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.
