So i am running the quick install

I am running split DNS. So internally, my dns reports a local ip address. But externally, it reports the public IP address. Perfectly fine and all works fine.
This apparently breaks your installer? and it abruptly breaks. I am not making this server internet accessible for now, was just trying to install https for use internally. dont see why it should fail here.
I re ran the installer without https now. and it seems to be installing.
