Could not read served logs 503 - but not using remote logs

[Anti0ff]

After some changes logs are not visible in Web-UI and try to get logs from URL - not local (and log-file in log-catalog in worker container is OK)

Airflow 2.7.3, installed in Docker (Portainer) with containers (and with proxy), CeleryExecutor

logging	base_log_folder	/opt/airflow/logs	airflow.cfg
logging	remote_logging	False	airflow.cfg

Error

f2ad1c31c101 
*** Could not read served logs: Server error '503 Service Unavailable' for url 'http://f2ad1c31c101:8793/log/dag_id=run_one_model_DAG/run_id=manual__2024-05-15T17:18:04.870528+00:00/task_id=one_model.model1_run/attempt=1.log'

worker_log_server_port = 8793 (in config, default)
volume "/opt/airflow/logs" is registered in all containers

Port 8793 was not in old version of docker-compose, but worked.

Where to find why 503 and why not local reading? Seems, all other modules in Airflow are working

Restart of Stack in Portainer not helped

"volumes" indicated in docker-compose in two blocks - first in "airflow-common" for include, second in "webserver" as is

x-airflow-common:
  &airflow-common
  volumes:
  - ${AIRFLOW_PROJ_DIR:-.}/logs:/opt/airflow/logs
...
airflow-webserver:
    <<: *airflow-common
    ...
    volumes:
    ...

And second dosn't contain volume with logs...
So after adding volume with logs in webserver section - all OK, logs are visible in UI

Something strange, why error is like logs are remote and code 503...
