Hello,
Sad news for everyone. YouTube/Google has patched the latest workaround that we had in order to restore the video playback functionality.
Right now we have no other solutions/fixes. You may be able to get Invidious working on residential IP addresses (like at home) but on datacenter IP addresses Invidious won’t work anymore.
If you are interested to install Invidious at home, we remind you that we have a guide for that here: https://docs.invidious.io/installation/..
This is not the death of this project. We will still try to find new solutions, but this might take time, months probably.
I have updated the public instance list in order to reflect on the working public instances: https://instances.invidious.io. Please don’t abuse them since the number is really low.
Title is kinda misleading. The issue only affects public instances, and it has been an ongoing problem since many months ago. Basically the moment youtube detects lots of traffic from one IP it gets blocked, and need sign-in.
It seems this block just became harder to work around, and they started blocking all IPs from hosting providers, but I’m sure a solution will be found eventually.
If you have a spare laptop/PC/raspberry pi you can host your own invidious in your home. It won’t get blocked, it will be much faster, and you can use options that are usually disabled on public instances (the API and DASH quality).
Then you can add something like tailscale/twingate into the mix to access it outside your home. Self hosted wireguard can also work if your ISP gives you a static IP or you setup a DDNS service. I personally use twingate because I don’t like opening any port in my router.
