What does it mean if my online 90-day report is rejected for the second time after reporting in person the first time?

A rejection of your online 90-day report could indicate several issues. First, if you've traveled abroad after your last report, you'll need to report in person again as your reporting schedule resets. Ensure you are within the correct time frame (between 14 to 7 days before the due date) for online submissions and check if your TM30 (reporting of residence) is up to date, as some immigration offices require a new TM30 for any overnight hotel stays in Thailand. If your previous reporting was too soon or related to an in-country extension, that might also affect your ability to report online.
