Try Freetube with VPN set to an uncommon location like Bulgaria or Argentina etc. This works for most videos, but still some won't load. I use invidious for those vidoes. This way, you won't overload the invidious instances.

The key is trying out different VPN locations.

This Invidious instance still works. Don't push it too hard, though: it's all we've got.

Also, if you log in to YouTube in Chromium or something (assuming you're on desktop) and then use yt-dlp with the --cookies-from-browser chromium argument, it should work. This is also possible on Android via Termux and iOS via iSH if you copy ~/.config/chromium to the app.

Freetube connecting to local invidous node.

Pick a server somewhere in southeast Asia. I don’t have issues with youtube with locations outside of western and first world countries.

I watch YouTube with FreeTube on the desktop, and Tubular on mobile. Both are always over VPN, and anonymous (not logged in).

I haven't logged into YouTube in literal years.

Totally agree with the FreeTube recommendation. Libredirect will even open links in FreeTube. I use IVPN and use non obscure servers but every once in a while I do have to try a different one.

You could also try Grayjay instead of Freetube

FreeTube has been working for me with Mullvad VPN set to Swedish servers. Also https://inv.nadeko.net/ if I need to share links with anyone.

TBH I just use youtube.com in my browser (Floorp/Firefox) with uBlock Origin. With SmartTube on my TV.

The alternative front ends or apps don't seem to support loading my watch history, playlists, or subscriptions, and they don't sync between my devices even if I manually import stuff. Making usability an absolute nightmare.

Librewolf/ublock origin

Freetube or Librewolf (preferably via DDG search)

Cycle through VPN locations until you get a winner if you get a block. It's annoying, but the purpose of a VPN is to let you look like you're anywhere. So find a good spot to watch YT and then just settle in.

I use Freetube + Tor.

SmartTube on TV and Newpipe on mobile, always VPNd.

I use Freetube on PC and some NewPipe fork AND Freetube on Android. The Android one has been breaking as of late. :-(
