Issue

Object store client periodically queries Instance Metadata Server (IMDS) for the IAM role and token. Occasionally, the IMDS server returns the credentials with very short expiry time than the minimum time expected. When this happens, the expiry time defaults to 0 seconds and never attempts to fetch the credentials again. The object store client receives Bad Request error when it tries to connect to the object store with invalid credentials. The EMS log capture this error, and it looks like
[OscLowPriThreadPool: object.store.unavailable:EMERGENCY]: Unable to connect to the object store "ObjectStore" from node VM1. Reason: Bad request.
