Any update to snapshot repositoruy requires to restart ES cluster

Elastic Stack Elasticsearch

We have observer that if we perform any change to snapshot repository or even hit a simple update repository API with exactly same setting we observe connection pool shutdown error or repository inaccessible error which only gets resolved after restarting ES. Is this expected behaviour?
We use IRSA for authentication with s3 bucket and es version 8.15.3

Hello,

This is not the expected scenario.
It could be related to the repository getting disconnected while updating the settings. Can we review this in logs or any issue with repository? Can we create a repository on linux host for testing & try updating this with API to understand if the issue is related with repository or anything from ELK end.

Thanks!!
