I followed this guide: https://wiki.nitrado.net/en/upload_own_minecraft_modpack
The server will just not start, I get this error message when I try to start the server: Currently there are some information missing to show this page. This happens when the gameserver is not fully started.
I haven't added the modpack I want to use yet, I just tried to start the server with forge installed, I downloaded Forge 1.12.2.
Any help is appreciated, thanks!
