Calendar not showing up on subdomains

My calendar events do not show up when accessing my subdomain. It works fine with https://www.coffeetimecomputing.com/blog/ but does not show events when accessing the site by blog.coffeetimecomputing.com. I have this same issue with another site. I can get this to work when changing my entry points on the bluehost. Is there a better work around. Any help would be appreciated.
