logging - 为什么 ariflow 登录 google cloud composer 突然出现 '[Errno -2] name or service not know' 导致的错误？

Question

我使用谷歌云作曲家气流来监控工作流程。经过一些工作流程后，突然日志没有出现在气流 UI 上。这是气流用户界面上的错误

*** Log file isn't local.

*** Fetching here: http://xxxxx:8793/log/etl-job-bq/influxdb_internet_usage_task/2019-10-01T01:05:00/2.log

*** Failed to fetch log file from worker. HTTPConnectionPool(host='xxxxx', port=8793): Max retries exceeded with url: /log/etl-job-bq/influxdb_internet_usage_task/2019-10-01T01:05:00/2.log (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f1a5f0d66d8>: Failed to establish a new connection: [Errno -2] Name or service not known',))

然后，我尝试查看 GCS 的气流日志，日志就在那里。但是来自谷歌云作曲家的气流未能在 GCS 上获取日志文件
