System Settings > Re-Check Configuration and everything passes, including “Default IPv4 address for virtual servers” but when I go to create a VS it says: “Failed to work out externally visible IP address”.
It’s not behind a router, but the nameservers are probably not propagated yet - not sure if that would make a difference to this though. It’s odd that the configuration check passes : /
I used System Settings > Networking Settings > Default IP address for DNS records > Same as virtual server IP to get it to work.
Also think I found the reason why it wasn’t working, we use different listening ports for Apache so it appears the correct port needs to resolve in order for it to work (so in the meantime use Same as virtual server IP as above`).
