Videos not playing in Chrome

Hi all, Our videos are not playing in Chrome. Error messages vary between machines (either cannot load m3u8. Crossdomain access denied' or 'error loading media file could not be played'. Sample here: https://publishing.rcseng.ac.uk/journal/video?doi=10.1308%2Fvideo.2016.1.1&videoTaxonomy=ULIMBVID Any have any ideas? Cheers, Matt
