SSL Pass-through yields SSL errors

Hi there.
I’m almost at the end of my tether here. I have no idea why this doesn’t work.
All I am trying to do is SSL passthrough which should be simple enough (or so I thought) but 99% of the time I am getting some unknown SSL error

root@kuroko:~# curl -k https://corihaws.co.uk
curl: (35) Unknown SSL protocol error in connection to corihaws.co.uk:443

I note this error does not occur if I set the default backend - so the issue must be with the rule but I’m clearly not understanding it.

Here is my config

global

        log /dev/log    local1 notice
        chroot /var/lib/haproxy

        user haproxy
        group haproxy
        daemon

Any help would be much appreciated.
