Hello @pasatmalo,
Welcome to the forum!
If you have a suspended node because of a low online score (less than 60%), then you need to fix this issue and keep your node online for the next 30 days to fully recover. Each downtime event requires additional 30 days to recover.
If you have a suspended node because of a low suspension score (below 60%), you need to figure out what’s causing this:
and fix this issue. It unlikely will fix itself.
This suspension score is growing back with every successful audit, so your node is failing audits for unknown reasons (if they are known, the audit score will be affected instead).
Thus this situation is more dangerous than being offline (except being offline for more than 30 days), failing audits usually lead to a disqualification at the end.
