Upload to CloudFront


So I’ve been trying to create a 360 video AR scene in Zapworks. I found out it requires CDN Links from CloudFront or CloudFlare. I tried CloudFlare it just won’t accept my payment and I can no upload anything. I tried CloudFront by simply opening s3, created a bucket, uploaded a video there and then went on CloudFront distribution and created a distribution thingy for the s3 Bucket. linked the links to Zapworks 360 video, then tried to preview it on my phone. Video just simply won’t load, its all black. or sometimes it loads for the first 3 seconds then it just loads forever. I need help… :((((
