Problem Description

Issue

I have been noticing issues surrounding connecting to servers running 1.20 of Minecraft, and I have traced the issue to my clients using IPv6 to connect but the server IP binding defaulting to 0.0.0.0 (IPv4). This is fine, however I can’t set it to listen on BOTH IPv4 and IPv6 interfaces, only one or the other. It says to leave blank to enable listening on all interfaces, but it is not possible to make the setting blank. I have resorted to manually editing the MinecraftModule.kvp file, however this change is often overwritten by AMP and therefore is not a good fix.

Reproduction Steps

  • Naviagte to configuration>server settings
  • Try to change Server IP address/IP binding
  • Try to set Binding to use both IPv4 and IPv6/all interfaces at once.
