我在问题中附上了错误消息

ERROR - Exception when executing SchedulerJob._run_scheduler_loop
Traceback (most recent call last):
  File "/home/centos/env_airflow/lib64/python3.6/site-packages/sqlalchemy/engine/base.py", line 1277, in _execute_context

    cursor.execute(statement, parameters)
psycopg2.OperationalError: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

Answer 1

PostgreSQL 数据库服务器意外关闭了连接。 查看 PostgreSQL 日志文件以获得解释。

在那里，您将找到解释原因的错误消息，或者您会找到类似的消息（意外连接丢失），这表明恶意防火墙或路由器中断了网络连接。
