Good afternoon dear Forge team, I would like to play a self-compiled modpack in version 1.12.2 with my friend on Nitrado. We always had this well-known io.netty bug there. I strongly assume that it is because I had the latest Forge version on my computer (I reinstalled mc -> no Forge version but problem still exists) but the server only Forge Vanilla v.14.23.5.2847 (1.12. 2). That's why I wanted to download this (and other Forge versions of this MC version 1.12.2, which would have worked) and wanted to install them, but then I always get this error (see below). And now I even have the problem that I can't install a Forge version at all, because this error always comes up. I hope you can help me.
