@Sri Thanks for reaching out to us, have you tried to recreate it? How does it work?

Generally, the error message you are seeing is indicating that the Azure Machine Learning Studio is having trouble reaching the workspace storage account.

This could be due to a number of reasons, but the error description suggests an issue with the authentication. Here are a few possible solutions:

1. Check your storage account settings: Make sure that the storage account associated with your Azure ML workspace is correctly configured and accessible. You can verify this in the Azure portal.
2. Check your network settings: If you have configured any Virtual Networks (VNet) or firewalls, ensure that the necessary services and IP addresses for Azure Machine Learning are allowed through.
3. Check the authorization header: The error message mentions an issue with the Authorization header, suggesting a problem with the signature. This could mean an issue with the access keys. You can regenerate the keys in the Azure portal and then update your application with the new keys.
4. Recreate the compute instance: As suggested in the error message, try deleting and recreating the compute instance. There might have been a temporary issue during the creation of the instance.

If you have checked on above details but still seeing this error, please let us know and we are happy to enable you a free support ticket to check on specific details of your setup. Remember that these changes can have security implications, so it's important to understand them fully before implementing.

I hope this helps!
