LibRedirect will automatically forward you to frontends like this for many sites. Now it can detect offline instances and keep trying others
if you’re technically inclined and like watching stuff, i highly suggest kodi with debrid addons. i have mine running on a raspi3b+ connected to my tv, it’s like netflix for everything. my debrid service is like $13 a month and has a terabyte cloud with rss torrent downloads, usenet, vpn, voip, and high speed downloads from premium services. don’t wanna advertise here but if you ask i’ll link you. or just search debrid
i’d suggest using your own instance for that
