Not able to fetch audio files

[zerootoad]

Description

Dont really know if this is my issue, the api issue or cpr itself but im not able to fetch audio files and download them as it gives me a 0 status code which means no response and an empty text, while if i tried downloading it using wget it would actually fetch and download the file.

bool utils::download(const std::string &url, const std::string &path,
                     const std::string &filename) {
  std::string fullPath = path + filename;
  if (std::filesystem::exists(fullPath)) {
    return true;
  } else {
    std::filesystem::create_directories(path);
  }

  auto ses = cpr::Session();
  ses.SetUrl(cpr::Url{url});
  auto ofs = std::ofstream(fullPath);
  auto r = ses.Download(ofs);

  std::cout << r.status_code << std::endl;

  if (r.status_code == 200) {
    std::cout << url << " downloaded\n";
    return true;
  } else {
    std::cout << "Failed to download " << url << std::endl;
    std::cout << r.text << std::endl;
    return false;
  }
}

wget output:

@zerootoad thanks for reporting. Could you please check the error object inside the response object?
https://docs.libcpr.org/advanced-usage.html#response-objects

Because inside there you find more detailed error information in case the status_code is 0.
