javascript - GET API call working in webbrowser or postman but not jquery -


i have issue since yesterday calling api jquery code.

when call http://sub.domain.com/congresses/id via web browser (chrome , safari), works fine.

when call same route via jquery call, "get http://sub.domain.com/congresses/id net::err_failed"

i didn't log in apache access.log nor error log (i host front-end , api).

here jquery code :

$(function(){         $.ajax({                 async: true,                 url: "http://sub.domain.com/congresses/17",                 datatype: "application/json",                 method: "get",                 crossdomain: true,                 success : function(data){                         populateapp(data);                 },                 error : function(){                         populateapp(local_data);                 }         });         addtohomescreen(); });

when run "developper server" on 3000 port, don't log when use jquery code.

i'm using apache passenger on ubuntu rails back-end , front-end runs on jquery-3.1.1

i tried use rack-cors did not change anything.

i disabled adblockplus plugin did not change either.

thanks
