cant authenticate odata feed VSTS

Hi Robert14358 ，
Per my test, I can connect to my own azure devops with the code you shared:

If so, make sure you are using the correct organization name and project name in your query.
Also make sure you are a member of the project with basic access or higher rights.
You could also ask the project administartors to run the query to check the result.
More information for your reference:
Connect with data by using OData queries - Azure DevOps | Microsoft Learn
Add users to organizations and manage access - Azure DevOps | Microsoft Learn

Best regards,

Joyce
