Reactivating your nodes is an easy process. Follow the 2-step method below:
The restore function will only be present until the end of the paid-for billing cycle. The node will cease to exist with no payment after the billing cycle ends.
For example, You have a node paid for until Oct 31 but cancel on Oct 14. You can restore the node if you change your mind on Oct 25. However, If you change your mind on Nov 10, you cannot restore it.
