We’ve confirmed that the problem occurs only in Safari and is tied to how Wistia’s player (our third party streaming service) is handled in that browser. Specifically, Safari blocks certain XMLHttpRequest calls that Wistia uses for its playback logic, which leads to the error you’re seeing.

We’re now working directly with Wistia to address this on their side and ensure consistent playback across all browsers.

We will keep all customers  updated as soon as we have a confirmed fix.
