I wanted to have a Minecraft mod server with my friends, followed tutorials. Ultimately (when I wanted to start it) it says something like "Illigal".
Now I'm scared and don't know what to do!

Have you already added mods?

No, I don't have a plan of screenshots or how to make them, but we can talk about discord maybe because it bothers me a lot without being able to play mods…
