Without this Plugin we can't use other plugins already on Aternos

Well, this is one error your system of rules has produced.

Instaling the plugin Dragonistan will cause the server to be unable to load it.

And guess what? One of the solutions is to install the plugin Kotlin4MC. _{(https://www.spigotmc.org/resou…-minecraft-plugins.58015/)}

Oh, but it seems you've blocked this plugin because it's download link is on an external website -_-

That renders Dragonistan completely useless because the other solution was to delete it.
