Dear Airflow community, 

not sure if I’m targeting the right audience here. Just trying though :) 

In a basic setup, like described here: 
https://www.cloudwalker.io/2019/09/30/airflow-scale-out-with-redis-and-celery/ 
<https://www.cloudwalker.io/2019/09/30/airflow-scale-out-with-redis-and-celery/>,
 using `airflow_version: 1.10.10`, I discover two issues: 

1) Even though the `airflow.cfg` is configured to use `CeleryExecutor` +Redis 
and all the logs mention to use it, there is no Task visible in Flower. When a 
DAG is started, it will only be processed via the DB

2) Many times, especially once a DAG is running, in the UI I see the warning 
"The scheduler does not appear to be running.”

Do you have any advice how to solve those?

Best, Andreas
