Answer 1

You are using this:
$tecnico = Tecnico::with('servicios')->where('Auth_Token',$auth)->firstOrFail();
In this case, firstOrFail throws Illuminate\Database\Eloquent\ModelNotFoundException exception if it doesn't find the requested model and hence it could be because the model with that Auth_Token field is not available.
Make sure the Auth_Token is right and that Auth_Token is available in your database. You may try a dd(Input::get('Auth_Token')) to check what you have recieved from the POST submitted by the user.
