Got the same error I Thailand. Quarantinehotelstaff was not able to help… I tried reinstalling, I tried editing with the same result: invalid information (the info is correct by the way)
So I ended up never installing it again and had no problems so far (I am in Thailand since six weeks) 🤷🏼
exactly what I experienced… I am in the train right at the moment. Hua lamphong is still operating for ticket service and a few trains still depart from there. Southbound trains depart all from bang bamru.
