cannot bind socket Multiple backends tcp mode

Hello List,

I hope someone can shed some light with the following situation:

Setup:
HAproxy frontend proxy and apache SSL backends. I didn't want to use haproxy+stunnel or apache mod_ssl so I use straight TCP mode and redirects, it works fine with one backend. The only problem is when I try to add a second backend for a different farm of servers I get the following:

"Starting frontend https-services-in: cannot bind socket"

My understanding was that multiple backends could use the same interface, perhaps I was wrong, if that is the case, any suggestions on how to be able to have multiple backends running tcp mode on port 443 so I can match the url and redirect to the appropriate backend from my HAproxy?

Thank You Very much in advance.
