Audio cutting off

I've recently published a scene of a course. On the last page, the audio from the video file inserted on that page is cut off approx. after playing half of the slide. I have done the same preview with other scenes of the course that worked perfectly. The audio works fine when previewing the slide in Storyline. See here (where I published the slide in question separately): https://elearning.kk.dk/hbr/driftsansvarligBrand/testKapitel3/story.html. There are no triggers nor cue points on that slide that could trigger this error. I have also tried to delete the slide, insert a new one, adding video and triggers over again, but it didn't help. I even published the video from Adobe Animate again, which didn't help either.
