ObjectLock s3 Bucket Backup and Aux copy issue

Hi All,

We have configured OL enabled s3 bucket and configured library and storage pool and policies using that s3 bucket and everything shows online and can be access from commvault console and also using CLI on MediaAgents. we also tested cloud test tool and that works fine too. But when we start a backup or Aux copy we are seeing below errors on the jobs
