How to debug WordPress site oneboxing?

AI-generated summary

User dylanb is experiencing issues with oneboxing links from their WordPress site, while other WordPress links work properly. They’ve tried debugging the process, sharing a link that doesn’t work and one that does, and checked the link with iframely, which shows no errors. robmc suggests a possible solution related to WPEngine, while pmusaraj wonders if Cloudflare might be blocking the Discourse user agent. dylanb confirms that a security setting was blocking the user agent, resolving the issue.

I have previously had no issues with onebox, but suddenly any links from my WordPress site aren’t oneboxing properly. They simply show the url (after the spinner tries to one box). Other WordPress links seem to work properly.

Is there a way to debug this process and see why the url isn’t embedding properly? I assume it is something with my WP site.

Doesn’t work…

Works…

Everything seems to show up properly here: Iframely URL Debugger - Open Graph, Twitter Cards, oEmbed

Edit: Just noticed you had checked the iframely already

Posted that link with the results above when I edited. Here’s the report and everything looks good (images, descriptions, etc.) nothing about an error or anything.

This might help you (see ref WPEngine)

Is umhoops.com using Cloudflare? I wouldn’t be surprised if some of Cloudflare’s features also blocked the Discourse user agent.

Thanks guys. You are correct that it was a security setting blocking the user agent. Thanks for quick responses!
