Getting 406 not acceptable status code with ajax post requests in production hosting.

Hi again! I did't know in wich channel put this (Vue, Laravel)...anyway...hope you can help me :) Well, I'm stuck on this:

I'm creating a full SPA with Vue.js using Laravel as backend service. I have two separated apps and I already dealed with CORS in Laravel.

I'm using Axios with Vue. In my local enviroment everything works fine, but in my production enviroment (a shared hosting) the only thing that is not working at the moment are POST ajax Json requests. I'm getting this Chrome message:

"POST http://cdmapi.tevilcon.com/api/units 406 (Not Acceptable)"

So, here are my test domains:

• http://cdmapi.tevilcon.com/api ---> backend API
• http://condominios.novotendencia.com ---> Front-end app.

Here is my CORS configuration in Laravel:

return $next($request)
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, PATCH, DELETE, OPTIONS')
            ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization');

The thing that annoy me is that my test post requests in Postman work perfectly :(. I even copied the Jquery code generated by Postman:

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "http://cdmapi.tevilcon.com/api/units",
  "method": "POST",
  "headers": {
    "content-type": "application/json",
    "cache-control": "no-cache",
    "postman-token": "697c597a-ed81-2d9e-914a-8f1752bb343b"
  },
  "processData": false,
  "data": "{\n\t\"title\" : \"This post request does not works\",\n\t\"description\": \"Yeahh...does not works\",\n\t\"icon\": \"car\"\n}"
}

$.ajax(settings).done(function (response) {
  console.log(response);
});

Does not work either. As soon as I build my Vue App and upload to the server I got the same 406 status code every time I do a post request (I removed the postman-token bofere that).

I was reading about that some hostings services have some rules denying some requests (using mod_security or whatever). But if Postman works with my API, so...what I'm missing? What does Postman different with the request?

Please feel free to access both of my test domains and see my issues ( don't hack my server :) )

Thanks!!
