Constant 90001/2 Disconnect since 6.3

[Silaven]

Since 6.3 I consistently am disconnected and sent to the title screen due to disconnect upwards of 10-12 times in a day. Essentially at random my Sending ping will drop to zero and i will disconnect though I have no actual hiccups or internet issues on my end.

Drivers are updated, Tried disabling firewall and didnt resolve, I maintain a 600MB to 1GB constant download and 300-400MB upload.

Anyone else having this issue? Any fixes? The game feels unplayable in this state.

Greetings Silaven,

The 90001/90002 error is usually associated with some sort of interference of game data or a connection issue. To start, I would recommend trying out the following troubleshooting:

- Please make sure any anti-virus software you have on your PC is temporarily disabled or has the appropriate exceptions made for FINAL FANTASY XIV.
- Running the game as an administrator.
- Within Microsoft Edge, you can try adjusting certain settings to see if it may help. Click the "Settings" option on the top right of the browser (under the three dots) and navigate to the "Privacy, Search, and Services" option. Once there, please go to the "Tracking Prevention" section, and make sure that it is set to "Balanced". If you have previously adjusted your Edge settings, it might also help to set it back to Default instead.
- Lastly, you can check/adjust the Port Ranges on your router to ensure that they have been opened. You may contact your ISP and request for assistance with opening them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

I hope this helps! Thank you for visiting the FINAL FANTASY XIV Technical Support Forums.
