What does status=canceled for a resource mean in Chrome Developer Tools?

Question

What would cause a page to be canceled? I have a screenshot of the Chrome Developer Tools.

Answer 1

Another place we've encountered the (canceled) status is in a particular TLS certificate misconfiguration. If a site such as https://www.example.com is misconfigured such that the certificate does not include the www. but is valid for https://example.com, chrome will cancel this request and automatically redirect to the latter site. This is not the case for Firefox.

Currently valid example: https://www.pthree.org/
