necroposting... Sorry! The link is dead, does anyone have an archive of it that's working?

I think it was one of the early versions around Minecraft 1.20.4.

You can't.

i tried with port 25565 and it worked. change it if you still have the problem, or get the right port from the server's website or forum if have any.

No one will be able to help you when all you post is an image of it not working. I bet it's an connection issue, which makes it unable to download the AI engine. Without log though, that is nothing we can tell exactly.

@sqwennyy Only for servers. Your game will always stay on 1.21.11 or newer.

@Plumer-Man how did u fix the script im having the same issue

Use a VPN. The internet filtering of the Russian goverment is causing this issue.

Thanks a lot.

The screenshot tells us nothing.
