Currently, YouTube videos that have been embedded using H5P activity display ‘Error 153’. The error occurs on Apple devices only but is in relation to the used device and browser. The problem applies to the newest version as well as older ones.

YouTube videos embedded in H5P content currently have limited functionality on Apple devices using the common browsers Firefox, Chrome, and Safari. On macOS, they can be played in Chrome and Firefox, but in Safari, error 153 appears instead of the video. On iOS and iPadOS, error 153 appears in Safari, Firefox, and Chrome.
The cause is a bug in WebKit-based browsers combined with a change in the guidelines for the embedded YouTube player. Unfortunately, there is currently neither a fix for the bug nor a solution from Moodle or H5P. As a workaround, please use a browser other than Safari and a device other than an iPhone or iPad on macOS.

During the specified period maintenance work will be carried out on the IT Center's MFA MySQL databases. The databases will be unavailable for a total of approximately 15 minutes during this maintenance and new logins to services with RWTH Single Sign-On will not be possible. Existing sessions will remain intact.

Maintenance is complete
