I am using RestTemplate to make a POST request to an external endpoint

        RestTemplate restTemplate = new RestTemplate();
        final String url = "https://jsonplaceholder.typicode.com/users";
        String jsonData = "{"title":"foo", :"body"::"bar",:"userId":1}";
        //Set Headers
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        //Create HttpEntity object
         HttpEntity<String> requestEntity = new HttpEntity<>(jsonData,headers);
         ResponseEntity<String> response =   restTemplate.exchange(url,HttpMethod.POST,requestEntity,String.class);
          return response.getBody();

i’m getting this error

I/O error on POST request for “url”: Connection timed out

i tried the solutions on similar stackoverflow questions using ClosableHttpClient it didn’t work, any help or guidance is appreciated.
