Meltano

Hello Team, I am using airflow version ==2.1.2 but not able to run daemon Process. Whenever i run the  meltano airflow scheduler -D command, it is not working and also it's not creating airflow-scheduler.pid file.
Write now i am getting  `address already in use Error` , I kill the all process but it still not working.
Wonder if anyone face this issue.

Are you able to see if there's anything else on that port at all? Which OS are you using?

This is the error i am getting.
``` result = pool._dialect.do_ping(fairy.connection)
  File "/home/ubuntu/rm-projects/meltano-projects/dev-vegamour/.meltano/orchestrators/airflow/venv/lib/python3.8/site-packages/sqlalchemy/engine/default.py", line 575, in do_ping
    cursor.execute(self._dialect_specific_select_one)
