getting timeout error when importing data from csv.

I have a csv file with 1k data in each file but it is giving timeout problem after 73 records only. any tweaks to speed up? i have used chunck as well and now after timout error it is working in background

my code is,

public function postUploadData(Request $request)
    {
        $request->validate([
            'uploadfile' => 'required|required|mimes:csv,txt',

        ]);

        $file = $request->file('uploadfile');
        $filename = $file->getClientOriginalName();
        // File upload location
        $location = 'uploads';

        $file->move(public_path() . '/uploadfiles/', $filename);
        

        $header = NULL;
        $dataset = array();
        $delimiter = ',';

        if (($handle = fopen(public_path() . '/uploadfiles/' . $filename, 'r')) !== FALSE) {
            while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE) {
                if(!$header) {
                    $header = $row;
                } else {
                    $dataset[] = array_combine($header, $row);
                }
            }


            fclose($handle);
        }

        $uuid = md5(rand(1, 10) . microtime());

        $createdata = [
                'file_name' => $filename,
                'type'  => 'uploadtype',
                'uuid' => $uuid,
                'upload_date' => date('Y-m-d'),

                ];

       UploadHistory::create($createdata);
    
       $chunks = array_chunk($dataset, 20);

       foreach($chunks as $dataget) {
           foreach($dataget as $data) {

        // for($i=0;$i<sizeof($data); $i++) {

             $jsonPayload = json_encode([[
