Last two weeks every time I use Piped I am getting error “Sign in to confirm you are not a bot”. It happens on every instance and videos work very rarely. It seems like Google enforces you to log in if you try watch lot of videos from one IP. I hope this will not be end of Piped and there will be solution for this problem.
Upd. I got similar problem on Invidious recently
Now I’ve tried almost all of them in the Piped instances list (Several domain name for sale and server not found errors) and only the smnz.de one works for me. :( I am wondering whether a freshly installed self-hosted private Piped video instance will work fine.
