file_get_contents(https://www.google.com/recaptcha/api/siteverify): failed to open stream: Connection timed out – CentOS

I have tried many solution but no one can help. I’m using google recaptcha for my laravel project and i’m using this library "buzz/laravel-google-captcha": "^2.2"

Here is it my code in view

<div class="col-md-6">
   @php($attributes = [])
      {!! Form::captcha($attributes) !!}
      @if ($errors->has('g-recaptcha-response'))
         <span class="invalid-feedback" style="display: block;">
                <strong>{{ $errors->first('g-recaptcha-response') }}</strong>
         </span>
      @endif
</div>

My code in LoginController

public function validateLogin(Request $request){
        $this->validate($request, [
            $this->username() => 'required',
            'password' => 'required',
            'g-recaptcha-response' => 'required|captcha',

        ]);
}

I got an error

file_get_contents(https://www.google.com/recaptcha/api/siteverify): failed to open stream: Connection timed out
