TigerVNC - xinit: connection to X server lost

I'm trying to run TigerVNC on my Arch Linux environment with XFCE but when I run it, it starts for some seconds with black screen and then closes.

The logs say:

Using desktop session xfce

New 'DESKTOP-LV4580H:1 (athena)' desktop is DESKTOP-LV4580H:1

Starting desktop session xfce

_XSERVTransmkdir: Mode of /tmp/.X11-unix should be set to 1777

In /etc/X11/tigervnc I have the following Xsession file:

#!/bin/sh
#
# Wrapper to run around X sessions.
# Based on lightdm
#

echo "Running X session wrapper"

# Load profile
for file in "/etc/profile" "$HOME/.profile" "/etc/xprofile" "$HOME/.xprofile"; do
    if [ -f "$file" ]; then
        echo "Loading profile from $file";
        . "$file"
    fi
done

# Load resources
for file in "/etc/X11/Xresources" "$HOME/.Xresources"; do
    if [ -f "$file" ]; then
        echo "Loading resource: $file"
        xrdb -merge "$file"
    fi
done

# Load keymaps
for file in "/etc/X11/Xkbmap" "$HOME/.Xkbmap"; do
    if [ -f "$file" ]; then
        echo "Loading keymap: $file"
        setxkbmap `cat "$file"`
        XKB_IN_USE=yes
    fi
done

# Load xmodmap if not using XKB
if [ -z "$XKB_IN_USE" ]; then
    for file in "/etc/X11/Xmodmap" "$HOME/.Xmodmap"; do
        if [ -f "$file" ]; then
           echo "Loading modmap: $file"
           xmodmap "$file"
        fi
    done
fi

unset XKB_IN_USE

# Run all system xinitrc shell scripts
xinitdir="/etc/X11/xinit/xinitrc.d"
if [ -d "$xinitdir" ]; then
    for script in $xinitdir/*; do
        echo "Loading xinit script $script"
        if [ -x "$script" -a ! -d "$script" ]; then
            . "$script"
        fi
    done
fi

# Run user xsession shell script
script="$HOME/.xsession"
if [ -x "$script" -a ! -d "$script" ]; then
    echo "Loading xsession script $script"
    . "$script"
fi

echo "X session wrapper complete, running session $@"

exec $@

This exec $@ executes the Exec=startxfce4 that is in /usr/share/xsessions/xfce.desktop.

How can I fix it?

Re: TigerVNC - xinit: connection to X server lost

A further information. When I run "sudo systemctl status vncserver@:1.service", It seems that the service starts and stops:
