Access Package Assignment Issue

Hello,

We have an access package that was functioning properly in the past, but the assignment process has stopped working.

The issue started on August 22; the last successful assignment was on July 29.
When attempting to manually assign the access package to an external user, we receive the following error:
"You don't meet policy requirements to request this entitlement."

Additional details:

The configuration of the policy has not been changed.
Users who can request access is set to “None (administrator direct assignments only)”.
Changing the “Enable new requests” setting (enabled/disabled) does not resolve the issue.
Expiration is set to 90 days.
This access package is intended for external users, but I tested assigning it to an internal user and it works correctly.

At this point, I do not have additional information about what might be causing the issue. Could you please help us identify the root cause and suggest next steps?

Thank you for your assistance.

Kind regards,
