Regular 90002 Disconnects

I've been having this issue since early Stormblood where my Game regularly 90002 disconnects, usually while transferring to/from any instanced zone. I can't go to housing areas, to my house itself, or in to any duty without the risk of a DC.

With the very long queues right now, this is making the game near unplayable for me.

I initially thought it was an issue with my ISP, but since someone else has started playing in my house and they're NOT having this issue, that's clearly not the case.

- My firewalls are disabled and FFXIV has an exception
- FFXIV is ignored by my Antivirus
- Windows Defender is disabled
- The necessary ports are opened and being forwarded

Yet despite my best efforts, I still regularly disconnect 4-5 times a day while zoning to or from an instance.

Is there anything else that could be causing this issue?

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

The troubleshooting we can provide involves strengthening your home network. I'm not sure if you have done the following, however, I'll list some other options just in case you've missed them.

1) If you are using a wireless connection, try connecting to your router/modem using an Ethernet cable.

2) Try a clean boot. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC. This will make sure that no background processes are interfering with the game.

3) 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.
- 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"

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