I'm wondering whether theres some way I can configure stunnel itself to pass some whitespaces or something back and forth every few seconds to make sure the session stays open and live?

I'm not sure what an ELB is actually doing and if this would help in
your case, but did you try to enable TCP_KEEPALIVE?
