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.
