URL: https://github.com/apache/airflow/issues/41171

   ### Apache Airflow version
   
   Other Airflow 2 version (please specify below)
   
   ### If "Other Airflow 2 version" selected, which one?
   
   2.9.2
   
   ### What happened?
   
   I have configured the airflow.cfg file and make sure the the Celery worker 
logs are stored in both the worker instance and the Amazon S3.
   
   The logs in S3 are stored in 
s3://${BUCKET_NAME}/airflow_logs/dag_id=xxxx/run_id=scheduled__2024-07-30T03:20:00+00:00/task_id=xxxx/,and
 logs saved in the worker instance with path 
${AIRFLOW_HOME}/logs/dag_id=xxxx/run_id=scheduled__2024-07-30T03:20:00+00:00/task_id=xxxx/
   
   When I check the Airflow UI for task retrieval, it cannot retrieve the logs 
from S3, but it can retrieve the logs from the worker instance. Logs are as 
below:
   
   ```
   ip-10-121-129-159.eu-west-1.compute.internal
   *** No logs found on s3 for ti=<TaskInstance: 
logstash_alice_etl.convert_euw1 scheduled__2024-07-30T03:20:00+00:00 [success]>
   *** Found logs served from host 
http://ip-10-121-129-159.eu-west-1.compute.internal:8793/log/dag_id=xxxx/run_id=scheduled__2024-07-30T03:20:00+00:00/task_id=xxxx/attempt=4.log
   [2024-08-01, 07:29:55 UTC] {local_task_job_runner.py:120} ▶ Pre task 
execution logs
   [2024-08-01, 07:30:03 UTC] {subprocess.py:63} INFO - Tmp dir root location: 
/tmp
   ...
   ```
   
   
   ### What you think should happen instead?
   
   The logs should be found in S3 instead of the worker instance
   
   ### How to reproduce
   
   configure the [logging] parts in airflow.cfg with the below modifications:
   
   base_log_folder = /opt/apache/airflow/logs
   remote_logging = True
   remote_log_conn_id = aws_airflow_euw1                  # Just an IAM 
connection to S3 in eu-west-1
   remote_base_log_folder = s3://${BUCKET_NAME}/airflow_logs
