Splunk Universal Forwarder fails port scans on AIX 7.1 servers

I have several AIX servers (AIX 7.1) with Splunk Universal Forwarder 6.5.2 that all fail Nessus port scans for allowing TLS1.0 on port 8089. All configs, verified by btool, have "sslVersions" and "sslVersionsForClient" set to tls1.2 and Splunk has been restarted many a time after making sure these configs are correct. Have several Red Hat Linux servers (RH 6) with same Universal Forwarder version and same SSL settings in the same configs, that do NOT fail port scans for any issues related to port 8089. Anyone encounter the same issue on AIX platforms? The AIX platforms all have OpenSSL 1.0.1e, while the Linux platforms have OpenSSL 0.9.8e-fips-rhel5 I appreciate any insight.
