@Arun SG For better understanding: May I know which version OS are using?
Can you share the screenshot of the error message?
Have you checked port 445 is enabled? Also refer the Prerequisites
Troubleshoot Azure Files problems in Windows and Troubleshoot Azure Files problems in Linux
This article provide How to mount Azure Files and List of Windows version and Linux Distribution list supported by Azure Files
For example: \anexampleaccountname.file.core.windows.net\example-share-name.
Additional information: Using AzCopy and Azure Storage Explorer tool are the best option to transfer data(upload and download) to Azure
Hope this helps!
