The logs don't say that the server aborted the connection; it says "someone" 
Only a network capture will help you determine which of the three entities 
aborted the connection.

Subject: [isalist] HTTPS Connectivity Issue

I created a simple server publishing rule in ISA Server 2006 that is configured 
to allow HTTPS traffic that hits the ISA Server's external IP address to access 
a server providing Secure FTP services (configured to use port 443, at any rate 
- and yes I know about 990 and 22).  However, when I attempt to connect, I get 
the following results.

Might anyone know why the firewall is aborting the connection?

I have a similar server publishing rule (uses FTP instead of HTTPS) that works. 
 The only difference between the two is the protocol that's allowed.

Also, the ERROR_SUCCESS issue perplexes me because of the paradox those two 
words together present. :)
