My 90 day on line rejected for first time this week. I have been successfully submitting my 90 day report on line for many years. I had to visit JOMTIEN imm office to do manually and ask why it was rejected this time. Answer was that their newly updated system incorrectly uses passport number in use at date of last entry into Thailand. I obtained my new passport many years ago and have never left the country since 2009. Immigration had transferred all my data from old passport to new passport in 2010. Their new system rejected my application this time because my passport number was not the same. The officer explained that she used to handle the on line applications herself, but now it is done by their upgraded computer system. She apologized and did provide me with the new 90 day report without asking for any documentation. I asked if the same thing will happen next time I submit my on line 90 day application. Her response was that she did not know. Be aware now if you have changed your passport number since last entering Thailand when you attempt to do your next on line 90 day report.
