PHP Post request working in Postman but not in React with Axios

• I have a server written in PHP and it have some routes
• The routes work fine with postman
• But when I use React with Axios it gives error
• Here is the PHP code

header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
header("Access-Control-Allow-Methods: GET,POST,DELETE,OPTIONS");
header("Access-Control-Max-Age: 3600");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");

and here is how I make request with Postman
This is my raw JSON data that I feed in postman

{
    "data1" : "data1"
}

This is how I make the post request with React and Axios

await axios("url", {
        data: JSON.stringify({ "data1" , "data1" }),
        method: "POST",
        headers: {
          "Content-Type": "application/json",
        },
      });

The url is same , but it’s giving network error

I want my axios request to get completed as it get’s completed on postman

I have also tried this config but not working

<?php


// Allow from any origin
if(isset($_SERVER["HTTP_ORIGIN"]))
{
    // You can decide if the origin in $_SERVER['HTTP_ORIGIN'] is something you want to allow, or as we do here, just allow all
    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
}
else
{
    //No HTTP_ORIGIN set, so we allow any. You can disallow if needed here
    header("Access-Control-Allow-Origin: *");
}

header("Access-Control-Allow-Credentials: true");
header("Access-Control-Max-Age: 600");    // cache for 10 minutes

if($_SERVER["REQUEST_METHOD"] == "OPTIONS")
{
    
    if (isset($_SERVER["HTTP_ACCESS_CONTROL_REQUEST_METHOD"]))
        header("Access-Control-Allow-Methods: POST, GET, OPTIONS, DELETE, PUT"); //Make sure you remove those you do not want to support

    if (isset($_SERVER["HTTP_ACCESS_CONTROL_REQUEST_HEADERS"]))
        header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");

    //Just exit with 200 OK with the above headers for OPTIONS method
    exit(0);
}
//From here, handle the request as it is ok
