Update...
Sorry for the real time debugging. I was stuck all day, I guess writing it out made me study it a little closer...
I noticed that I was using setUseEPSVwithIPv4(true) which was sending an
EPSV
229 Entering Passive Mode (|||62110|)
Removing that has allowed me to move a little further, now I'm getting
Total Bytes To Send: 1033

The secondary server is trusted, as it is one of their DMZ servers. Now to get around this one...

Looking for debugging advice, or a clue as where to go with this.
I have been using this code base for quite a while internally. I had a new need to do client authentication to an external site, and I managed to connect and successfully login, but anytime I enter passive mode, the socket times out.

I can connect successfully using other products (cuteFTP and FlashFXP), so I don't believe it's a firewall issue, but what I did notice, is that the products do TLS renegotiation? on the Data Connections. I don't see that happening in the FTPSClient code.

Removing the setUseEPSVwithIPv4(true); was the key here.
To get past the server verification you need to use setRemoteVerificationEnabled(false);
I was successfully able to send a file to the remote system.
Sorry to anyone who was actively looking at this...
