This is caused when your request response is not received in given time by timeout  request module option    Basically to catch that error first  you need to register a handler on error  so the unhandled error won t be thrown anymore  out on  error   function  err       handle errors here        Some more explanation here   In the handler you can check if the error is ETIMEDOUT and apply your own logic  if  err message code      ETIMEDOUT        apply logic        If you want to request for the file again  I suggest using node-retry or node-backoff modules  It makes things much simpler   If you want to wait longer  you can set timeout option of request yourself  You can set it to 0 for no timeout
