• I’m signed in to my account and i verified that the --cookies are not expired. and of course my date of birth is over 18 years.

• I know that there is an age-restriction in the EU region, but i also can’t download using just the normal command as with all other age-gated videos.

• What gives?

My issue(#28468) ended by @dstftw because the cookie seems to be expired. but as I wrote in the issue, it was the fresh cookies.txt. This is not going to happen in the United States, so this is unlikely to be fixed.

• My cookies are not expired too.

• Does that mean the contrubutors are unlikely to fix any issues that occure outside the US

You are probably connecting from EU, right? A change to YT was announced ~4 month that there will be extra steps for age verification in EU, iirc. If you connect from outside of EU, it should work.
