Repeated Crashes with Error 90002, 2002

In the last few weeks, the game client for FFXIV has been crashing with error 90002 sporadically while I'm in instances. I first noticed it while trying to complete MSQs in Heavensward and repeated got disconnected, leaving me to attempt and reattempt what would have been as easy duty on Paladin.

Since then, I have created and played a new character, in hopes that it was just an issue with that specific MSQ, and found that that character, too, is also repeatedly disconnecting in instances. It is at the point that the game is becoming unplayable: I cannot progress easily if at all. I am able to reconnect and rejoin the game almost immediately, unless I also receive a 2002 error while logging into the data centre. This drops me out of the game completely, and requires me logging back in.

I'm on the Sargatanas server, and play using PC. I have sent in an email ticket and received a response, indicated below.

Here are some troubleshooting steps that should resolve your connection issues. Please take all the steps.

The issue you are describing is most associated with interference with the game data. Most of the time, it results from certain security/privacy changes on Internet Explorer. Other times it occurs when an application that is running in the background is causing interference, such as Anti-virus software, firewalls, media players, web browsers, etc.

Please make sure all background applications (including anti-virus programs such as Norton, Kaspersky, Windows Defender, etc.) have been disabled and/or closed to minimize game interference.

Ensure that the latest version of Internet Explorer is installed on your PC (even if you don't use Internet Explorer), please do not use Edge as that is a different internet platform. Once Internet Explorer is up-to-date, please open the IE browser, open the "Tools", go to "Internet Options" and adjust the following settings:
Under the "General" tab, please delete ALL browser history.
Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
Under the "Privacy" tab, please move the slider to the lowest possible settings or to "Allow All Cookies"
Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED.
[SSL 3.0 should be UNCHECKED]
Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
Right-Click on the FFXIV launcher icon and select "Properties"
Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
Hit "Apply", then "OK" to save the changes.
Please RESTART your PC now.


Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

If the suggestions provided above do not resolve the issue, then there is a communication error.
Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

*You may learn how to do this by visiting http://www.portforward.com/
Find your specific router's brand and model number from the 'List of Routers' and you will be provided a step-by-step guide on how to access these port settings.
Otherwise, your ISP may forward these ports for you.*

I have followed all the steps outlined above and this issue still occurs. It did appear that the steps here helped, as I was able to complete a Sastasha dungeon this morning without a disconnect, but that proved false when I ran through in Copperbell and nearly wiped the party on multiple occasions with my repeated disconnects on healer.

I've restarted my PC a number of times, FFXIV has been restarted (of course), ipconfig has been used to flushdns... but I am running out of ideas and options on my end. It is true that my ISP is not the greatest, but I have never had issues such as this with other games or mmos.

Please look into potential issues with the client. I am saddened that a game I enjoy, and continue to pay for, is becoming less so. I'm disappointed that I have spent money on an upcoming expansion that, at this point, does not appear that I will be able to play. I am hoping the disconnection issues that have cropped up are not permanent and can be fixed soon.

If there is anything else I can do on my end, please do let me know.

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When did this start happening? Do you recall anything changing/updating on your PC that coincides with this?

It sounds like you have a relatively stable connection. Any drops are short, but enough to completely disconnect you from the game.

The suggestions we provide are to alleviate any troubles with your home network. If they have solved the issue, it may stem from somewhere along your route to the server. In this case, we'd recommend contacting your ISP and making a report.

Have you tested the game on any other devices or other internet connections?

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
