I'm not sure why but for the last 2 days I've been getting error 90002/90001 every few minutes. Never had this issue before, didn't change anything and I haven't had any connection issues with anything else, the game just suddenly decided to be unplayable for no apparent reason. I see a lot of other threads on the forums reporting the same issue but haven't found any solutions, really just want to get some answers from SE on this.
Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.
Please try the following troubleshooting steps:
- The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, 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, click “Advanced” and select ‘Accept’ under both First Party and Third Party 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.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
-Make sure your fire wall or antivirus program is not interfering with the game
- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.
