I work for a division of Honeywell International which operates and supports an IBM Systemz mainframe system running the z/VSE V4.2 Operating System. We are running the latest maintenance levels of all components there. I have been using FileZilla for several years to perform FTPS (FTP over implicit TLS/SSL) transfers from my workstation to/from the z/VSE host's SecureFTP server. Recently the Honeywell Global IT Security team which approves software for use within our environment approved FileZilla V3 for use. Previously I had been using V2.2.32 and based upon the new approval upgraded to V3.2.0.
Using V3.2.0 I can not successfully get past the TLS/SSL handshake when trying to connect to the z/VSE host. V2.2.32 still works fine. I am attaching the "Debug" logs from both V3.2.0 and V2.2.32.
Thanks in advance for your support.
