Could not resolve host

[SujuanWu]

I also met the issue Error in curl::curl_fetch_memory(url, handle = handle) : Could not resolve host: s3-cn-north-1.amazonaws.com; Name or service not known", and I also try to run get_bucket("mybucket", region = "cn-north-1",check_region = F) or get_bucket("mybucket", region = "cn-north-1",verbose = T), the error still appeared.
