Problem Description

Issue

I have had no issue being able to connect when my instance is set up as a vanilla server. But when I try to set one up as an ATM10 server I am unable to connect. I keep getting the Internal Exception: java.net.SocketException: Connection Reset. I am unsure about how to get a full modpack working and the things I’ve been trying to follow online haven’t really been successful so far. Any help guidance would be appreciated this is my first time using AMP.

Reproduction Steps

  • Uploaded the ATM10 server pack to AMP and extracted files
  • Turned on the server
  • Failed to connect
