So i have configured nxlog with https to talk with logstash. 
I got an error on nxlog side " ERROR unexpected data from server (64 bytes)" 
I looked it up and it looks like nxlog got https://github.com/lamby/pkg-nxlog-ce/blob/master/src/modules/output/http/om_http.c#L6462 

So i did check up the http input on logstash side , but i have not understand it 
https://github.com/logstash-plugins/logstash-input-http#L118
Looks like logstash should send respond code, but i dont see it. Remember i dont have ruby skills. 
Can someone explain to me what might be wrong here ? Or how to fix this issue ?

Can you get a traffic dump to see what logstash sends back to the client side?
