# VPS not working

> Connection, password, load, disk, IP on blocklists

The IP, login (`root`), and password come from the server card in the [@lumivps\_bot](https://t.me/lumivps_bot) bot. The default OS is Ubuntu 22.04, and you connect as `root`.

<AccordionGroup>
  <Accordion title="Can't connect over SSH/RDP" icon="plug-circle-xmark">
    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.
  </Accordion>

  <Accordion title="Lost password" icon="key">
    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](/en/vps/backups) ahead of time). Don't want to lose data — write to [support](/en/support).
  </Accordion>

  <Accordion title="A site on the server won't open" icon="globe">
    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.
  </Accordion>

  <Accordion title="Server is slow" icon="gauge-high">
    Check the CPU / RAM / disk load inside the OS (`top`, `htop`, Task Manager). Hitting the plan's limits — upgrade through support.
  </Accordion>

  <Accordion title="Out of disk space" icon="hard-drive">
    Symptoms: services crash, logs stop writing, `No space left on device` errors. See what's full:

    ```bash theme={"system"}
    df -h
    du -sh /var/* | sort -h | tail
    ```

    Logs and the package cache are the usual culprits:

    ```bash theme={"system"}
    journalctl --vacuum-size=200M
    apt clean
    ```
  </Accordion>

  <Accordion title="IP on blocklists" icon="ban">
    Check the reputation at mxtoolbox.com/blacklists.aspx. If problems persist, request an IP swap from support.
  </Accordion>

  <Accordion title="Need an additional IPv4" icon="network-wired">
    There's no dedicated button in the bot — request it through [support](/en/support).
