Hi @mrmarie ,

As mentioned in the same KB article (https://help.duo.com/s/article/1337?language=en_US), if your organization uses Duo’s Microsoft Azure Active Directory Conditional Access application, you may need to add the following Duo hostnames to your allow list, depending on the location of your organization’s Duo deployment:

• Canada deployments: cc1.azureauth.duosecurity.com
• EU deployments: ec1.azureauth.duosecurity.com and eu-west.azureauth.duosecurity.com
• US deployments: us.azureauth.duosecurity.com
• AU deployments: ase2.azureauth.duosecurity.com

Hope this helps!
