CF pages site not working as intended

Hi being first time using Cf pages, I tested it locally which seems to be working correctly, however on pages, part of the page is not loading, to be more specific, the page contains some videos files which are part of the wordpress gallery plugins (are all converted statically), I compare the page source files, all identical to each other which makes me suspect that it might be due to the file size limit which I’m not 100% clear, all my files are under 10m individually (mainly .mp4 files), but the single page I’m having problem loading has this video gallery, so I’m not sure if this exceeds the file size limit hence the loading problem?
