90002 Error Rendering Game Unplayable

For 2 months now I've been getting kicked out of the servers seemingly at random with the 90002 error. I've reached the point where I'm not going to pay for a game I can't play. Steps I've taken:

1. Rebooted modem
2. Reinstalled FF14
3. Switched from ethernet to WiFi
4. Changed DNS
5. Switched to a different ethernet cord
6. Verified my ethernet port/cord is not damaged by using different modem in different home and experiencing no issues.

No one else in my home is experiencing any issues with internet at all, and the only issues I have are in FF14. We have not changed ISPs and Spectrum is reporting no issues on their end. It would be super sick if I didn't have to stop playing my favorite game because of some bizarre technical issues completely unrelated to me but after nearly 3 years of subtime, the frustration of seeing everything on my screen stop moving and none of my abilities registering trumps whatever onze of fun I can manage to scrape together.

I originally tried to submit this in-game but, wouldn't you know it, I can't stay connected long enough to use it!

Greetings fellow Eorzean,

I'm sorry to hear that you have been experiencing persistent 90002 errors for the past couple of months. Also, thanks for providing me with a list of troubleshooting methods that you have already tried. Here are a few things I would recommend trying, as it may help with your constant disconnects:

1. Please make sure all background applications (including anti-virus programs) have been disabled or closed to minimize game interference before attempting to log into the launcher.

2. Please adjust the following settings in 'Internet Options' in the Control Panel:
- 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.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC after. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator".

3. Lastly, check to see if the following port ranges are opened on your router. You may contact your ISP for assistance with opening these port ranges for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

I hope these steps are helpful! Thank you for posting in the FINAL FANTASY XIV Technical Support Forums.

Steps 1 and 2 were completed successfully. As for step 3, I'm not very familiar with ports but I followed a guide online and I'm more certain than not that if the ports weren't open before, they are now. Unfortunately, I still got the error. Just now, at the end of a Tam-Tara run.

Just received a response from the email support team and they've told me the issue lies with my ISP, so I will be cancelling my subscription. You may mark this resolved.

Greetings adventurer,

Thanks for providing us with an update of the issue, and I'm sorry to hear that the issue persists. If you have properly configured your router and connected to the modem directly via a wired connection, and are still experiencing this issue, then it may be best to contact your ISP for further assistance. In the meantime, I'll go ahead and move this thread to the 'Separate Support Required' subforums.

We hope they will be able to provide further assistance with this issue!
