bug description

Hey,

I've host my own instance of cobalt and tried to get yt downloads to work.
I have verified that the requests actuall go throug my instance but I still get the following error message:
file tunnel empty or I get a file with 0B in size.

I can also confirm that my IP is not banned from youtube.

reproduction steps

self host cobalt
add it as an instance on cobalt.tools
try to download a yt video

screenshots

No response

links

platform information

Chrome 142.0.7444.176 on Windows 11

additional context

Does anyone has the same issues?

Do I have to do extra work to get youtube to work?

And yes I've read the pinned issue but this only includes their instance and not self hosted ones.
