Hi @Prachi Trivedi ,

Thank you for posting query in Microsoft Q&A Platform.

It seems something changed in your Storage account networking settings that's causing this issue.

Could you please check below thread where detail steps are there to handle storage network settings and try same and see if that helps?

We experience the same issue since the 10th of november. Our filesystem linked service Host field was always set with drive letter 'S:\shares' but for some reason this doesn't seem to work anymore. This setup was working fine for more than a year and according to documentation I am not doing anything wrong.
