Images not loading over HTTPS

We’re having an issue with https://tholabiotech.com/. When we had the website loading over HTTP everything loaded perfectly but as soon as we installed the plugin and loaded everything with HTTPS the images stopped showing… This is even with using the Mixed Content filter as well as Fire mixed content fixer with different method

All the images are in the Media Library EG: https://tholabiotech.com/wp-content/uploads/2021/06/Untitled-1-1.jpg can be found over HTTPS but won’t show on the front end
