I can't figure this one out. Everything was running well. I don't see anything in the access or error logs that indicate a problem (some of the sites don't even have error logs yet).
Via Virtualmin, I can go to services --> preview website and then the site loads just fine.
If I try to access the same site via it's URL, I get the refuse to connect error. Some are one domain, some are subdomains of that domain, some are completely different domains.
What should I be looking at to debug this?
