Why Is My New Subdomain Not Working?

--Remember, once you add a subdomain, it must propagate just like your domain had to do. Subdomains can take 24-72 hours to fully propagate across the internet and locally on the server. If your subdomain has not resolved after three or four days, try deleting it and re-creating it. Then, wait an additional few days for it to re-propagate.
