What happened?

After upgrading to airflow 3.0.1, remote logging is not working as intended.
I have set airflow.cfg for remote logging as below:
remote_logging = True remote_log_conn_id = s3_conn delete_local_logs = True remote_base_log_folder = s3://my-logs remote_task_handler_kwargs = {"delete_local_copy": true}

But airflow ui fails to fetch logs for both cases, triggering with ui and cli. Also the tasks are marked as fail.
["Could not read served logs: Invalid URL 'http://:8793/log/dag_id=init_test_3.0.1/run_id=manual__2025-05-21T02:10:37.485869+00:00/task_id=print_time/attempt=1.log': No host supplied"]

However, when i run airflow dags test with cli, my tasks succeed, but still fails to read logs.
["Could not read served logs: HTTPConnectionPool(host='ip-172-29-XX-XX.ap-northeast-2.compute.internal', port=8793): Max retries exceeded with url: /log/dag_id=init_test_3.0.1/run_id=manual__2025-05-21T02:15:10.539747+00:00/task_id=print_time/attempt=1.log (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0xffff73126db0>: Failed to establish a new connection: [Errno 111] Connection refused'))"]

I can see the remote logging has not been configured properly, but I don't know why.

What you think should happen instead?

I expect my tasks my tasks to succeed and the logs are fetched remotely from s3.

How to reproduce

remote_logging = True remote_log_conn_id = s3_conn delete_local_logs = True remote_base_log_folder = s3://my-logs remote_task_handler_kwargs = {"delete_local_copy": true}
