Bustle has a custom domain for hosting shortened links, it’s bsl.io. This used to work, but now none of the meta information is captured in the card validator, and I get the message “Unable to render Card preview” and a warning that there is no meta content being found. If we use a bit.ly link there isn’t an issue. Here’s one example of our link not working but bitly’s do, http://bsl.io/PVm http://bit.ly/1eGwQAU
EDIT: Our links worked up until recently, and our servers our fine and nothing has changed on our end.
