Oracle Database 2FA

I recently protected an application (Oracle Database) with a RADIUS type. I am running my DUO auth proxy on Windows Server. The implementation is working fine as expected when my users go through Toad or SQL Developer tool. However, some of my Oracle DBAs now experiencing authentication errors when they make connection to the same Oracle Database using code through a Jboss server, where their credentials are being passed through an .xml file. Has anyone experienced the same or know some resolution to this?
