the "" some people see in their logs if they don't bind to a
specific IP (I can't reproduce this, unfortunately).  Maybe the same
workaround will help in your situation.

So try "Listen xxx.xxx.xxx.xxx:80" if it's not like that already.  If
you need to bind to multiple IPs you can still do that with multiple
