To Reproduce
Steps to reproduce the behavior:

1. Run install script:

## Install dependencies
apt update
apt -y --no-install-recommends install curl git sed

## Install Git LFS
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | bash
apt -y install git-lfs

## Download and install SteamCMD
cd /tmp
curl -sSL -o steamcmd.tar.gz http://media.steampowered.com/installer/steamcmd_linux.tar.gz
mkdir -p /mnt/server/steamcmd
tar -xzvf steamcmd.tar.gz -C /mnt/server/steamcmd
cd /mnt/server/steamcmd

# SteamCMD fails otherwise for some reason, even running as root.
chown -R root:root /mnt
export HOME=/mnt/server

## Install SteamSDK using SteamCMD
./steamcmd.sh +force_install_dir /mnt/server +login anonymous +app_update 1007 validate +exit

# Set up 32 and 64 bit libraries
mkdir -p /mnt/server/.steam/sdk{32,64}
cp -v linux32/steamclient.so /mnt/server/.steam/sdk32/steamclient.so
cp -v linux64/steamclient.so /mnt/server/.steam/sdk64/steamclient.so

## Longvinter setup
# If not using auto update and gamedir exist, remove it
if [ ! "${AUTO_UPDATE}" ] && [ -d "$HOME/longvinter-linux-server" ]; then
    echo -e "\nDelete game dir\n"
    rm -r $HOME/longvinter-linux-server
fi

# Clone Longvinter Dedicated Server repo or do auto update if activated
cd $HOME
if [ ! -d "$HOME/longvinter-linux-server" ]; then
    git clone "https://github.com/Uuvana-Studios/longvinter-linux-server.git"
elif [ "${AUTO_UPDATE}" ]; then
    echo -e "\nUpdating gamefiles\n"
    cd $HOME/longvinter-linux-server
    git config pull.rebase false
    git restore .
    git stash
    git pull "https://github.com/Uuvana-Studios/longvinter-linux-server.git" main
fi
chmod -R ugo+rwx $HOME/longvinter-linux-server/

# Create base config if not exist
if [ ! -f $HOME/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini ]; then
    echo -e "\nCreating game config\n"
    cp $HOME/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini.default $HOME/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini
    if ! grep -q "ServerTag=" "$HOME/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini"; then
        sed -i '/^ServerName=.*/a ServerTag=Default' $HOME/longvinter-linux-server/Longvinter/Saved/Config/LinuxServer/Game.ini
    fi
fi

echo -e "\nLongvinter Dedicated Server successfully installed!\n"

2. Start the server by command: /home/container/longvinter-linux-server/Longvinter/Binaries/Linux/LongvinterServer-Linux-Shipping Longvinter -Port={{SERVER_PORT}} -QueryPort={{QUERY_PORT}}
3. Wait util try to create session.
4. See error.

Expected behavior
CreateSession: Successfully created session
