You may have a problem where you can't gain access to LxAdmin. Although everything else looks to be working fine. You can restart the LxAdmin service on the VPS without effecting httpd or uptime.
Login to your VPS server via SSH as root.
Run this command:
/script/restart
If this does not work, reboot entire VPS via solusvm
If you think LxAdmin (Kloxo) is corrupt run this command:
/script/upcp
That will reinstall while keeping current settings.
