Start by asking our community for help via [Discussions](https://github.com/orgs/iptv-org/discussions). It is quite possible that someone already has a link to the channel you need and they just haven't added it to our playlist yet.
Xtream Codes streams tend to be very unstable, and often links to them fail very quickly, so it's easier for us to initially exclude them from the playlist than to search for expired ones every day.
