ERR_EMPTY_RESPONSE in Codeigniter

Question

When I tried to access my website it shows an error lke

This Page Isn't Working

www.abcdef.com didn't send any data

ERR_EMPTY_RESPONSE

and showing this error for a few seconds it will redirect to original page.

In Google chrome console it showing following error

POST https://www.abcde.com/Is_here/1542792525 net::ERR_EMPTY_RESPONSE

net::ERR_EMPTY_RESPONSE
send @ jquery.js:9566
ajax @ jquery.js:9173
jQuery.(anonymous function) @ jquery.js:9322
(anonymous) @ place:2255
setInterval (async)
(anonymous) @ place:2253

and the code in which error occurs is

setInterval(function(){ 
var c = "<?= TIME() ?>";
  $.post("<?= base_url() ?>Is_here/"+c,{a:"<?= $this->uri->segment(4) ?>",b:c,e:"<?= $this->uri->segment(5) ?>"},function(l_i){
			  
		  });
	  },10000);

err_empty_response was not the error from framework or website script.
