The "Token not validated" error when creating an Azure Blob container is typically an authentication or permission issue related to the Shared Access Signature (SAS) token or the Azure Active Directory (Azure AD) credentials being used.
The simplest fix is often to regenerate a new SAS token with a clear expiration time and the correct permissions. If using Azure AD authentication, confirm that the user or service principal has the correct Azure Role-Based Access Control (RBAC) role assigned at the proper scope (e.g., Storage Blob Data Contributor at the storage account or container level).
