Description:
Trace file for Forum report https://forums.mysql.com/read.php?39,701665,701665#msg-701665

Attached is a WireShark file showing the error.  Lines 1-14 are trying to connect from Z/OS, line 15+ are for the same application connecting from a Windows system.
In this case the target sever is a MariaDB because that is the system with WireShark, but I get the same results when the target system is a MySQL server.

How to repeat:
Try to connect to a MySQL server running on Windows from an application running on IBM's Z/OS.
