Enabling ethernet caused ONLY FFXIV NA/EU datacenters to have constant 90006/2002 err

Im at my wits end here and ive tried so many things for a ton of hours

Before this, everything was working fine. I am a Singaporean player playing on the NA datacenter.

I bought an ethernet cable and enabled the ethernet port, and started using Ethernet for the first time

Everything else is working fine - Destiny 2, Tower of Fantasy, Maplestory, Microsoft Edge, etc, as well as logging into the JP datacenter

However, trying to log into the NA or EU datacenters causes repeated 2002 errors/doesnt allow me to login. I did manage to login at some point, but proceeded to get 90006 errored afterwards. Using a VPN stops this.

I have tried many things such as repeatedly resetting my router and PC, putting my PC on a DMZ server, setting my IP address Static, Setting my DNS to google servers, and a few other things such as disabling all firewalls. However, none of these have resolved this issue.

Furthermore, for some reason, this broke my ability to play on wifi as well. I took out the ethernet cable and disabled the ethernet ports, however I still run into 2002 errors trying to login to NA/EU.

From using Tracert in command prompt it seems I have a double NAT, but I dont think theres a way to fix that (I tried setting my Orbi to Access Point mode) and it works fine on JP datacenter

Help would be appreciated

Greetings Adventurer!

We would be happy to assist with your concern. Please try the following troubleshooting to see if this helps with the connection issues you are experiencing. Open the control panel of the PC and go to ‘Network and Internet’. Once there select ‘Internet Options’.

- 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 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

Next, 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.

Lastly, we suggest to power cycle the console and router by shutting down the PlayStation 4/Router and leaving the power supply unplugged for 5-10 minutes. 

- Flush DNS: Within the "Command Prompt" of the device, please type the command "ipconfig /flushdns".
- Reset TCP/IP: Also within the Command Prompt, type the command "netsh int ip reset" and then restart the computer.
- Delete the Patch Folder: Navigate to the folder using this path This PC > Docs > My Games> FFXIV ARR > Downloads > FFXIV patch (Use for either the version update error or cannot download patch files error)
Then either rename or remove the folder, the next time FINAL FANTASY XIV is launched, the client will repair the folder.
- Change local DNS: Please try changing the local DNS server to 8.8.8.8 and 8.8.4.4
- Delete local files with corrupted character data, please note this will not delete the associated characters.

If you do not see an improvement, please feel free to respond to this thread for further troubleshooting.

Thank you for visiting the FINAL FANTASY XIV Technical Support Forums!

Are you on Singtel? Many of us experience the same 2002 error yesterday. Check out the other thread titled 6.3 packet loss.

Yes I am on Singtel, huh, thats just a major coincidence then, unfortunate

Yeah when I read you said it disabled wifi too then its probably not related to your ethernet cable. Same issue for me yesterday for about 2 hours. Should be fine now but if not I use VPN. Its been quite unstable for the past 2 weeks. Chat more in the other thread there are other Singtel users there.
