Published video plays for ~20 seconds then stops but previews to the end
Like the title suggests, I'm having an issue with a video. In preview mode, it previews perfectly from start to finish. I had a previously published this .story for web (including the video) and it went great! I made a minor change to the .story and republished it (the change did not even take place on the slide with the video) and now the published version plays the story up through about 20 seconds of the video and then stops completely.
I've seen other threads talk about security settings but this doesn't feel like the case because 1) a previous version of this .story worked well and 2) the video plays for a while but then just stops at the exact same point every time I try to preview it or re-upload the published files.
