NetScaler Administrator Login

For 2FA on Citrix ADC Management/Console access, has anyone gotten it to work with Duo? Trying to get the Duo passcode to be accepted as the 2nd factor using the Duo Auth Proxy as the Radius and it’s not working. We can successfully test network connectivity to the Duo Auth Proxy. But we aren’t getting any further in the process. LDAP works fine. The user authenticating can log in fine with their username and password + Duo passcode to servers.

Anyone have any ideas?
