I'm trying to create a FIX application that interfaces with ICE using Stunnel to provide encryption.

I'm encountering a handshake failure trying to interface with the FIX application.

I've copies portions of the Stunnel configuration file as well as the entire FIX configuration file below.

Can you do a quick review of the two configuration files and tell me what I'm doing wrong?

Both FIX and Stunnel are running on the same Windows 10 virtual pc.
