VSFTPD FileZilla GnuTLS error -15 (unexpected TLS packet was received)

I set up two new CentOS 7 boxes simultaneously, so the configurations should be identical, just different ip addresses and host names. I installed VSFTPD and configured for passive ports. One box connects fine, no issues, however the second box continuously throws me this error: GnuTLS error -15: An unexpected TLS packet was received. Here is the debug FileZilla trace: Status: Connecting to 192.168.20.68:21... Status: Connection established, waiting for welcome message...

I know the problem IS NOT SELinux, as I disabled that. The problem is also not the firewall, as I tried disabling the Firewall Daemon (firewalld). Here is the relevant portion of the /etc/vsftpd/vsftpd.conf file. listen=YES listen_ipv6=NO pasv_enable=YES pasv_max_port=10100 pasv_min_port=10090 pasv_address=192.168.20.88 ssl_enable=YES allow_anon_ssl=NO force_local_data_ssl=YES force_local_logins_ssl=YES ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO ssl_ciphers=HIGH require_ssl_reuse=NO rsa_cert_file=/etc/ssl/private/vsftpd.pem rsa_private_key_file=/etc/ssl/private/vsftpd.pem I did a Google search but did not see any 15 error codes. Thoughts?
