I am getting an error opening a Workbook in Data Science Experience. The last time I opened the workbook was four weeks ago, but now I am getting an error
{"asset_id": "1478e765-f4a5-4104-b704-38e098c451ee", "message": "Error when retrieving credentials from https://iam.ng.bluemix.net/oidc/token: Retrieval of tokens from server failed."}
Is there anyway to recover the workbook?
