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.
The first game was pretty good, but ran like shit for several years and was full of glitches…
Considering how broken games release these days, and now adding denuvo, I think it’s gonna be a hot pile of garbage. I would delay getting it for a 2 years after release date at this point.
