michalmisiewicz opened a new issue #11394: URL: https://github.com/apache/airflow/issues/11394
SQLAlchemy engine configuration is not passed to FAB based UI. Faced this issue when running Airflow with MySQL metadata store with wait_timeout = 120. Webserver is failing with Internal Server Error due to "[MySQL Server has gone away](https://docs.sqlalchemy.org/en/13/faq/connections.html#mysql-server-has-gone-away)" error. Settings like `sql_alchemy_pool_recycle` and `sql_alchemy_pool_pre_ping` have no impact on FAB internal communication with MySQL. **Apache Airflow version**: 1.10.12 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
