User story

Reporting this bug to hopefully get more eyes than my own on this issue.

Game

Core Keeper

Linux distro

Ubuntu 22.04

Command

command: start

Further information

I've recently setup a Core Keeper server on my self-hosted LXC running Ubuntu 22.04.

The server uses a rathole client as a tunneling proxy which I have setup and used for my other services including Minecraft, Valheim and VRising.

When passing the public IP address of my tunnel into the start parameters of the servers LGSM config the game crashes with a Segmentation Fault error. This error doesn't occur however when passing the default 0.0.0.0 IP address.

This error also doesn't occur when directly executing the _launch.sh in the server files which leads me to believe it's a LGSM issue.

While I'm unsure of what is causing this issue, I've looked through the command_start.sh executable in the modules folder and have noticed it passes the start parameters through tmux and also confirmed that Core Keeper doesn't have any IP related command line arguments in their documentation.

Still fairly new to the module and config side of LGSM so I apologies if I've missed something.
GitHub issues are also not my forte so I might of completed this wrong.

Steps to reproduce

Go to and edit ~/lgsm/config-lgsm/serverinstance/serverinstance.cfg
Add the lines, ip="PUBLIC_IP_ADDRESS" (any IP address will cause this issue, including your own public IP address)
Execute the command ~/serverinstance start
