Thank you for posting your query on Q&A.
For your query, it seems you are trying to access resources in your organization that require admin approval.
With the reference of error message, it usually appears when an application requires admin permission to access resources within your organization which is only an admin can grant.
In your case, it seems that the Autotask Client Portal application is trying to access resources in your Azure environment.
If you have an admin account in your organization Azure environment, you can sign in with that account and grant permission to the app for yourself.
For other users in your organization, you can Grant tenant-wide admin consent to an application.
If you don’t have an admin account, you can request admin consent from your organization’s administrator.
I hope this information helps! please Feel free to ask any questions you may have.
