Sorry only just coming back to this. Yes I use HAProxy on the front 🙂

Do I need to do anything special on the Discourse side to enable IPV6?

On the HAProxy side I believe I have changed everything I need to, specifically:

`bind *:80`  
to  
`bind :::80 v4v6`

and

`bind *:443 ssl crt /etc/haproxy/certs/`  
to  
`bind :::443 v4v6 ssl crt /etc/haproxy/certs/`

On [http://ready.chair6.net](http://ready.chair6.net) everything passes except for:

> IPv6 Connectivity - FAIL - Could not connect (to site) on port 443 over IPv6.

Any idea what I might be missing?
