Since it looks like your Online score took a hit too: could it have been a simple connectivity issue? Like whatever hiccup caused the online test to fail also made an audit connection fail (so it didn’t get ‘bad data’ it got ‘no data’?)
If you do not have a data loss and errors related to GET_AUDIT and GET_REPAIR, then your node should recover the audit score.
The online score will be recovered after 30 days online. Each downtime requires additional 30 days to recover.
