I am 100% sure that my ISP does not block any content, although I’ll try with the CF VPN now. Besides, the issue rather is that a zero second clip with no width or height is returned. I have tested this on macOS, iPadOS, and iOS. 
Hello there, I have a question regarding MP4s hosted on pornlemmy, I can never seem to load them, what’s up with that? They just give me a black screen whenever I visit from pornlemmy’s website, on my Memmy client or through my home server’s own UI, even when I go to the link directly.
