   > Hi, @potiuk Thanks for your response. I went through issue https://github.com/apache/airflow/issues/28010 which concerns why Sentinel doesn't work with TLS setup. However, this issue is related to the error we get when passing multiple sentinel URLs.
   
   > Expectation: Multiple sentinel URLs should be accepted per Celery [documentation](https://docs.celeryq.dev/en/stable/getting-started/backends-and-brokers/redis.html) .
   
   Yes - and as you can find in https://github.com/apache/airflow/issues/28010 - they seem to be accepted for the user there. Just SSL configuration seems to be not working. In any way this means that Celery Sentinel (for whatever reason) is not working wiht current Celer approach of Ariflow. I would appreciate if you and other users of Celery could help to investigate why and possibly helped to solve it together. This is the fastest way you can help and give back to the community for the free software you get - you seem to be technical enough and have celery sentinel to test it with and incentive to get it working. PRs fixing that are most welcome. And it is best to keep it in a single open issue (linked to that one so that one is not lost and you can see it refers to the same case). 
   
   In short: 
   * Yes, it seems there are issues with sentinel
   * It's better to consolidate it in one issue
   * Since this is a niche case, that might become impotant, as a community we'd appreciate those more technology savvy users who want to use sentinel to help with diagnosing and solving it. 
   
   Any help there is much appreciated.
