How can i send a post request to api with my shared hosting's ip

Here's my code block.

It's sending the request and when i check the response i saw the ip is my pc's external ip.

I must send it from my shared hosting.

public function testing(){
        $response = Http::acceptJson()
        ->withHeaders(['Authorization' => 'Bearer Token'])
        ->post('ip',[
            'user'=> 'user',
            'pass'=> 'pass!'
        ]);
        return dd($response);
    }
