Parallels remote application server

Trying to setup OTP with Parallels RAS.
When I enter credentials and the PIN I get : Access denied Wrong Username or password.
The log shows the bellow :

Could someone advise ?

The upstream LDAP server is rejecting the provided credentials as incorrect. Take a look at your directory server’s events, and double-check your password.

You can also enable debug logging on the Duo proxy server for more details.

Here’s a guide to interpreting the Duo Authentication Proxy debug output.
