I wanted to play my Modpack with my friend on a Server, i rented nitrado with 6gb and i just am not able to connect

 

To install my the modpack on the server i did everything exactly like it said on this page

https://wiki.nitrado.net/de/Eigenes_Minecraft_Modpack_hochladen

 

In singleplayer it works and on multiplayer it says can't connect to server

 

if i try to join it sais

with port i found in properties "io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information"

with standard port "Internal Exception: java.io.IOException: Eine vorhandene Verbindung wurde vom Remotehost geschlossen"
