Something went wrong Storyline 360 encountered an error while trying to publish

Hey CJLu​,

Sorry to hear that you're having trouble publishing from Storyline.

Based on the error message, Storyline is failing while processing a temporary video file. You can tell from the “.hls” and “.ts” file path in the Temp folder. This usually points to a specific video from the course that may be corrupted. 

The next step is to identify which video in the project is causing the issue. I understand this course may have multiple videos, but there’s a fairly efficient way to narrow it down:

1. Create a copy of your .story file.
2. Delete half of the slides, then try publishing.
   1. If it publishes successfully, the issue is in the slides you removed.
   2. If it still fails, the issue is in the slides that remain.
3. Continue halving the slides until you pinpoint the exact slide.

Once you've located the problematic file, and if including it is still necessary, I suggest re-encoding the file with a tool like Handbrake. This video outlines the steps for that process.

Let me know how it goes!
