 to verify certificate. This may be an issue with the remote host or with Excon. Excon has certificates bundled, but these can be customized:
      `Excon.defaults[:ssl_ca_path] = path_to_certs`
      `ENV['SSL_CERT_DIR'] = path_to_certs`
      `Excon.defaults[:ssl_ca_file] = path_to_file`
      `ENV['SSL_CERT_FILE'] = path_to_file`
      `Excon.defaults[:ssl_verify_callback] = callback`
          (see OpenSSL::SSL::SSLContext#verify_callback)
      `Excon.defaults[:ssl_verify_peer] = false` (less secure).
