If you don’t know which kind of restart to choose, try them in the following order and check if the restart fixed your issue.

• Reboot (hard) it is equivalent to restarting the operating system, so there is no physical shutdown. Reboot first terminates running processes, reboot (hard) resets the system immediately. It is suitable for solving some software issues within the OS.
• Poweroff (hard) is the equivalent of physically shutting down the computer, with Poweroff first terminating running processes, white Poweroff Hard shuts down the VM immediately. It preserves system resource allocation, so system restarts are quick. It is suitable for solving some software issues within the OS that cannot be solved by Reboot, and when upgrading the VPS ON.
• Undeploy (hard) frees up system resource allocation in addition to physical shutdown (Poweroff). Restarting is slower than from Poweroff. It is suitable for solving some virtual-hardware issues.

Undeploy may cause file system corruption or data loss.

Common VPS ON restart issues include:

• VPS ON doesn’t boot up after restart

Issue: VPS ON doesn’t boot up after restart.

Solution: If the server does not start for more than 10 minutes or is in an unusual state, contact support via the form. Include the name of the service, the type and purpose of the reboot, and the displayed status or error message.
