## How to Resync Node

The node might go out of sync if it fails to receive new blocks from the
network. In this case, the node would ideally automatically sync without any
manual intervention.

However, if the node is unable to resync on its own, it will need to be launched
again in a fresh mode (i.e. clean start). Please refer to the section
[Preparing the node](staking-ssn-setup.md) at Getting started
page
