Usually there is an option to change the BOOT IN RESCUE MODE
but you also need to know what your doing (mount, chroot, etc...).
If rescue mode is not working (no ping) it's because there is a hardware problem
you need to create a ticket for a support request and just in case have backups !
When you've entry level dedicated server (10-15€) always have backups on local computer or another server
because support could tell you : "We'll give you another server but not possible for doing a recovery"
