Problem Description
Issue
I cant Install any modloader/modpack for minecraft. Ive dove so my things.I even installed the server on my PC(works fine there) send it via SFTP to the server and now i cant start because a) minecraft_server.jar is missing (well install it then) or b) because amp say there is an error and its my fault. For a “simple” server hoster with a quote “focus on ease of use through its intuitive user interface and simple setup process.” i am screaming.
Reproduction Steps
- Install new Instance
- choose any forge/FTB server installer and install it
- Try to run the server
