How do I fix "This content isn't available. Try again later." On YouTube with their new ad-block blocking?

uBlock origin > Open the dashboard > Filter lists > Uncheck uBlock Filters > Check uBlock filters

This will force an update & reapply the filters. Usually the first thing you should try when issues like this pop up

I've been using FreeTube for years, it does break from time to time but never for very long, and it's a much nicer experience all round.

i just use yt-dlp to download the video these days. i have lots of filters in addition to ublock's default ones, somehow they're clashing with youtube and i can't properly play any video. yt-dlp+mpv is also much faster on my potato system, and makes me save videos.

by issue with ublock getting blocked, always try updating the filter lists

I also use Firefox with UBlock and I'm able to view YouTube content via m.yotube.com. Maybe loosen your UBO settings a bit?

I'm getting this since a few days and just refreshing the page always works

I ran into this for the first time today, and for some reason the video that didn't play in Firefox with uBlock Origin downloaded just fine with yt-dlp

1. Disable Enhanced Tracking Protection in the little padlock (on the Firefox URL bar, not somewhere in uBlock Origin)
2. If you've got a VPN, try disabling it. YouTube likes to be very heavy-handed with their blocking if I have my VPN on vs. not
3. Clear your cache. For some reason this can help sometimes, idk why. Can be beneficial to sign out and in again, too. (try Firefox settings > Privacy & Security > Manage browsing data > search "youtube" and delete too.)
4. Reload your uBlock filter lists in settings (un-select, then re-select)
5. If you're not signed in, this'll make things a million times worse. YouTube, especially nowadays, loves to block clients without a login because they're often used by video downloaders, AI scrapers, etc.

Other than that, there's not much else. Sometimes switching to a chromium-based browser helps too, but I doubt you want to have to entirely switch browsers any time you want to watch a YouTube video.

I use a vpn and change my location to Mexico and all the videos work again.

Use a flamethrower, that way you'll never have to deal with YouTube's anti-adblock stuff again

Use one of the few Invidious instances that still exist while that's still an option, although I have a bad feeling this sorta thing is screwing with Invidious too because I've had a few streams corrupt when skipping through the vid before.

Grayjay is also an option, while it's still an option.

I find https://preservetube.com/ to be useful when nothing else works.

I never saw this or any ad on YT, using only the Vivaldi trackerblocker and uBO Lite, also the Vivaldi adblocker works fine, but is discovered sometimes by the antii-adblock algorritm from YT. Anyway not possible to avoid the promotions from the Youtuber itself (not confuse with embedded sponsorblocks, which are filtred), also not posible to watch vids "only for members" which are appearing more and more, but I think it's a legit manner to create incommings for the authors.

Is it the first time you’ve encountered this? If yes, they’re likely testing something and you happened to be randomly selected. It should work again the next day. If not, try refreshing your filters.

I just reload the tab, ublock lite on Vivaldi.

Try disabling the quick fix filter. It worked for me.

Use GrayJay.

Use noutube instead
