Embed Youtube Video - Error 153

Hi TatyZF​,

Sorry to hear you're having trouble embedding YouTube videos in Storyline.

Using the same iframe you shared, I tested the playback on my end. After publishing to Review 360, the video played without issues in Google Chrome. Are you encountering this error after publishing your file? In Storyline, website videos cannot be previewed. They will only function after the course has been published. However, Storyline alerts authors with a generic "Web Video is unavailable during preview" message.

The Error 153 you're experiencing can be caused by network security or browser-level restrictions blocking YouTube's embedded player. Please try the following troubleshooting steps:

• View the published output across multiple browsers.
• Try an incognito/private browser window.
• Temporarily disable any browser extensions you may have installed.
• Test the published output on a different network (e.g. a mobile hotspot).

If the video works in any of those scenarios, that would indicate a local network or security setting is blocking the embed.

Let me know how it goes!
