access to azure blob storage using filedatastore no longer works

I am having difficulty accessing azure blob storage using

Location='wasbs://[e-mail]/FILEPATH'

ds = fileDatastore(Location,'ReadFcn', @load, 'FileExtensions',Extension )

I keep getting the error:

Cannot find files or folders matching: 'wasbs://[e-mail]/FILEPATH'

this is confusing for me as the files and folders definitly exist. and this function has worked in the past. I have set the MW_WASB_SECRET_KEY and MW_WASB_SAS_TOKEN Keys environment variables correctly.

Hi @Sandy, these troubleshooting steps might help solve the issue:

• Please make sure that the environment variables are set within the same MATLAB session where you are running your code.
• Also, check that your SAS token or secret key has the right permissions for the files or folders you want to reach.
• Ensure that your system has network access to Azure Blob Storage endpoints.
• Try using the basic datastore function:

ds = datastore('wasbs://[e-mail]/FILEPATH');

If this command does not work, it likely means the problem is with the connection or the file path, rather than with fileDatastore.

• Additionally, you may find this tool helpful: https://www.mathworks.com/matlabcentral/fileexchange/69906-matlab-interface-for-windows-azure-blob-storage

Hope this helps!
