Firstly i run command celery -A tasks status to look up worker status,it shows
celery@a-1746838028-bddjl: OK
celery@a-1746838028-kd24k: OK
celery@a-1746838028-n4prl: OK
celery@VM_0_7_centos: OK
celery@VM-167-209-ubuntu: OK
Then i look up worker status on flower web ui, it shows that celery@a-1746838028-bddjl worker status is offline.
maybe issue in celery #4758 has some clue
Downgrading gevent to 1.4.0 solved the issue for me
