Celery 5.5.0 broker connection recovery regression despite documented fixes

Despite upgrading to Celery 5.5.0 based on documentation stating broker connection issues were fixed in the latest version, the same broker connection reset and recovery failure issue recurred. This indicates a regression or incomplete fix in the broker reconnection logic for Redis.

When evaluating Celery version upgrades for broker connection stability, verify the specific issue resolution in release notes and test thoroughly in staging. Do not assume general 'broker connection fixes' resolve all connection recovery scenarios. Monitor post-upgrade for recurrence of connection issues. Consider reporting detailed reproduction cases upstream when documented fixes do not resolve specific scenarios.
