After configuring the notebook server, encountering the below error while opening Notebook from Portal:
Error opening notebook. Server machine 'https://hostname:7443/arcgis/sharing/rest/content/users/portaladmin/addItem' returned an error. 'Error: The index service seems to be unavaliable. Please check the index service.'
- re-indexing portal didn't work.
- any lead would be appreciated. Thanks.
