[AWS] RADIUS status suddenly changed from "completed" to "failed"

[Kevin-Mit]

Hi Team,

Based on this manual - https://aws-quickstart.github.io/quickstart-duo-mfa/, we tried to toubleshoot MFA "failed" status.

In the log - UpdateDirectoryServiceMfaSettings - e.g.
/aws/lambda/Duo-MFA-1012-UpdateDirectoryServiceMfaSettings-asF0qFKKPrSs

It returned "Radius updated successfully" after the first 6 creating attempts, then the MFA status in directory service became "completed", but subsequently it became "failed" after 3 creating attempts, and they're in the same chain. below is the snapshot of the log.

Could you please check this? any support will be appreciated.
