Thanks for the insights.
I had to step out for a bit and checked the link on my phone (Safari browser) with the surprise message “Congratulations, you installed Discourse”… I just tried again on Chrome on my laptop to result in getting the default Plesk screen again. I removed 24 hours of cache and now it is showing up on my laptop as well.
I guess it was either that or my DNS just didn’t refresh at the time I was trying.
Thanks again, I will probably be around with more “new user” questions.
