IPv6 is still a mess of compatibility issues, and being an early adopter is not always fun. I had a really weird problem where Youtube videos were unwatchably laggy on my home desktop PC. Gigabit hard-wired connection. Every other streaming site worked great, ditto every other device I owned. Even downloading the videos on the same device using yt-dlp worked great. After much tearing of hair, I noticed that in the network tab for attempting to watch Youtube, all of the requests for video data that were laggy were going to IPv6 addresses. So I turned off IPv6 at my network adapter and everything worked great after that. I guess Youtube and that PC and browser were the only things that supported v6, every other site, device, and Python dropped to v4 and worked fine. I guess I could dig deeper into what really went wrong and try to fix it, but I feel like I've already spent enough time and headaches on it. The off switch is just easier.
