I do too except the "connection refused" can happen for a normal person accessing the site. A DNS challenge could get the cert but still have this access problem.
Still, we don't know who all is affected. Maybe it's just people outside their hosting local region which might be ok.
I found the most recent thread we worked on this. You can see the browser failing to get the home page and quickly reload and see the expected home page (in that case just a landing page for new site).
