You could start trying with the same version of curl on both platforms. It
does sound like a bug or something.

It could also help if you could show us what command line parameters you were
using to get the different behaviors.

--trace is your friend and should more or less remove the need for a https
sniffer.

Compare trace outputs first. Try the same version of curl on both platforms.

If possible, write together script to run on your own server that receives
the request you send to the bank and compare that both requests look fine.

Are you using -A to set the User-Agent field for your requests?
