We, the Discourse team, did not create the one-click install, and much of what it does is a black box to us. As such, we limit the support provided here on Meta to those that follow our official install instructions, as we know how they work and how to troubleshoot. There are simply too many unknown variables with the DO one-click.
Note that it is a low-priority, long-term todo on our list to look into taking over the one-click install. However, as of now, there is no formal timeline to do so.
