Re: [D] The scheduler does not appear to be running. Last heartbeat was received 15 minutes ago. The DAGs list may not update, and new tasks will not be scheduled. [airflow]

GitHub user enchant3dmango added a comment to the discussion: The scheduler does not appear to be running. Last heartbeat was received 15 minutes ago.  The DAGs list may not update, and new tasks will not be scheduled.

Can't help with the provided info, but I think you should check the storage and memory in the Airflow host, whether it's in a container or on your device.

I faced the "The scheduler does not appear to be running" issue several times back then, and the root cause was either out of storage or out of memory.
