### Apache Airflow version 3.0.0 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? Hi. I use docker-compose and want to run Airflow with subpath, like `AIRFLOW__API__BASE_URL: ' http://mycompany.com/airflow'` UI is loading fine, with subpath provided, but when I trigger any dag it stucks in queued state. Worker logs are empty - just info that it is ready `2025-04-24 14:12:55.240510 [info ] celery@00da0db4ba2e ready. [celery.apps.worker]` Then after a while it gets ServerResponseError: Not Found ``` err = ServerResponseError('Not Found') response = <Response [404 Not Found]> ServerResponseError: Not Found ```  ### What you think should happen instead? _No response_ ### How to reproduce Use official docker compose and add `AIRFLOW__API__BASE_URL: ' http://mycompany.com/airflow'` env variable ### Operating System Debian ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
