Problem with R2 and domain name

Hello, I have a problem using R2 and Superstreamer (GitHub project). It allows converting videos to HLS format, and I tried it with a video for an intro. At first, everything was working fine with my subdomain, but since this morning, I've been having issues. It won't work with the subdomain or even with the main domain. However, when I remove my domain and try with R2 dev, it works without any problem. I don't understand why. Here are some images. So my question is: do you know how to fix this problem? I really need it as I work exclusively with this.
