This error code has also happen to me it will happen in 30-45 mins then take me back to the character selection screen and as I try to get back online it gives me a different error code and also says status 0. I look into solutions one of them being deleting the user folder cuz maybe some of the files in the user folder of ff xiv maybe corrupted another being that if you use wifi it will most likely kick you out . I try the deleting the user folder of ff xiv it didnt help but when i went back to connecting to my router via ethernet cable my problem was solve I have not gotten the error code for the past 2 days so hopefully it was the wifi issue .
