First, EFF has announced the end of support for Certbot on Windows. You may want to consider switching to a different ACME Client. See This Link for the announcement along with migration path.
As to this problem, a cert challenge request for alexpublishing.com is being redirected to ww12.alexpublishing.com. You use the Apache plugin which should have updated your Apache to handle the request without redirect.
To me it looks like this redirect happens by something in front of Apache. Maybe a router or firewall of some kind. Are you sure HTTP requests to that domain reach the Apache server?
Because usually we see other response headers when Apache used. Sometimes we don't but that is rare. For what it's worth, the ww12 subdomain is handled by nginx but that shouldn't even be involved. And ww12 looks like some sort of parking service.
Even requests for the "home" page get redirected to ww12
