TosRUs video mixed content

Having an issue with the TosRUs lightbox. Video’s are loaded as mixed content. (Using Vimeo) while I add the https version of the url. Now the video’s are not displaying.

In the jquery.tosrus.min.all file links are httpss (what is wrong), changed it but it is still not working.

Example output:

Mixed Content: The page at ‘https://www.websitename.nl/video-portfolio/’ was loaded over HTTPS, but requested an insecure resource ‘http://player.vimeo.com/video/98225249?api=1&player_id=tos-uid-1’. This request has been blocked; the content must be served over HTTPS.
