I was testing out downtify and I tried it on one with an explicit song and it says I can’t because it’s age restricted and I did everything get my cookies there but it still says I can’t. If anyone else has figured it out please share what you did.
I believe Downtify pulls the audio source from YouTube in the background, so the age restriction may actually be coming from YouTube, not Spotify/Downtify directly. Downtify also has an open GitHub issue for age-restricted content and cookies, so this may be a current app bug rather than something wrong with your setup.
I would first check the container logs and confirm the cookies file is actually mounted inside the container where Downtify expects it.
You can verify with:
docker ps --format "table {{.Names}}\t{{.Image}}\t{{.Status}}"
Then check the logs:
docker logs <downtify-container-name> --tail=100
Also make sure you do not post or share your cookies file publicly, because it can contain login/session data.
At this stage, if normal non-age-restricted songs work but explicit/age-restricted ones fail even with cookies, I would report it on the Downtify GitHub issue with the logs, because it may need a fix in the app or the downloader it uses.
