Usually only the online score should be affected.
However, if your node cannot provide a piece for audit after 3x attempts with 5 minutes timeout - this audit will be considered as failed.
But I also see that the suspension score is affected too - this is mean that your node responded with unknown error on audit request.
I would suggest to check your logs for errors related to GET_AUDIT/GET_REPAIR to see what’s going on. Unfortunately the node wouldn’t detect failures because of timeouts, but you may try to calculate the time between start and finish for the same piece.
