I have a primary domain. In order to configure phabricator, I set up a subdomain for it.
Everything worked fine. I was able to use phabricator as expected. But, there was a setup warning that asked me to configure an alternate file domain and recommended using a completely different domain name than the primary domain name for security reasons.
Thus, I bought a new domain by the name of After that I signed up for cloudflare and added this new domain. The domain status on cloudflare shows active.
From my phabricator install, I set up alternate file domain as :
bin/config set security.alternate-file-domain https://primarydomaincdn.net
The command ran successfully. However, after setting this up, when i access my <phabricator.primarydomain.com>, all the styling of the page is lost. It only loads plain html page with no css.
When inspecting via chrome developer console, the error says - it cannot load core.pkg.css file.
Is there a step missing here or do i need to wait? Its less than an hour since i signed up in cloudflare.
