I've been having this problem since I first started with FF14. I disconnect exactly every 3 hours with a 90002 error. The disc can happen very shortly after I first log in or it may take a few hours to occur, so I assume there is no correlation with my actual playtime. I don't experience this kind of connection issue in any other game and I play lots of different games online. At first I thought this was due to the server location being in USA (I'm playing from Germany), but after the server relocation it kept happening. My antivirus programm has FF14 greenlit everywhere and my internet conn is supposed to be "excellent" as it says on the start menu screen ingame. What can I do?
