FAQ

If Debian or Ubuntu does not move for a long time, it means that the panel IPv6 has not been adjusted properly; Debian needs to be restarted to take effect. Some VPS cannot be adjusted and can only be deleted and reopened.

After Debian is finished running, automatic restart will take effect. If the connection is really lost, it is likely that IPv6 is not enabled on the panel. Don’t be afraid of losing connection. Just go to the Oracle background and restart the VPS.
