I'm getting this same error on almost every video on each instance I try (Firefox 118.01) This renders the piped video unwatchable (they just fail). I am trying plugins that disable CORs, but they aren't working so far.

I can confirm that the issue is still occurring for me. I doubt that it's caused by a CORS misconfiguration, as it seems that some requests to my pipedproxy server succeed while others randomly fail.

I'm getting it right now on piped.video on every video I try. Firefox 124.0 on Win10. Reproduces with extensions and tracking protection disabled.
