The IP, login (root), and password come from the server card in the @lumivps_bot bot. The default OS is Ubuntu 22.04, and you connect as root.
Check: the server is powered on in the service card; the IP / port / login / password are correct; a local firewall or antivirus isn’t blocking the outbound connection. The standard SSH port is 22.
To reset the password, use the Password button in the server card: it sets a new root password without reinstalling. If you’ve lost access entirely, Reinstall helps — it installs a fresh OS and a new password, but wipes all data (Backups ahead of time). Don’t want to lose data — write to support.
Check: the web server is running and listening on ports 80/443; the A record points to the correct IP; the firewall isn’t blocking traffic. Lumi doesn’t set up the site itself.
Check the CPU / RAM / disk load inside the OS (top, htop, Task Manager). Hitting the plan’s limits — upgrade through support.
Symptoms: services crash, logs stop writing, No space left on device errors. See what’s full:
df -h
du -sh /var/* | sort -h | tail
Logs and the package cache are the usual culprits:
journalctl --vacuum-size=200M
apt clean
Check the reputation at mxtoolbox.com/blacklists.aspx. If problems persist, request an IP swap from support.
There’s no dedicated button in the bot — request it through support.
