Continuous 90002 error

Hello,

- I have not been able to play the game for three days due to uninterrupted disconnections (I get a 90002 error ~10 seconds after I enter the world).
- I play on PC (Windows 10) with the Steam version and all expansions activated.
- I have played more than 1000 hours since January without any problem before this one.
- I have a good Internet connection (optical fiber) which works fine for every other service than FFXIV.
- I do not use a VPN.
- When I get to the lobby, the server connection is displayed as Excellent.
- I tried every suggestion from this post but to no avail.
- I reset system settings and uninstalled/reinstalled the game but the problem persists.
- I did not change any network, firewall or antivirus settings recently (FFXIV has obviously been allowed by the firewall since I started playing).

Can I get some support on this issue?

[EDIT]
- The problem seems to be limited to my character Cole Porter on the Alpha server (EU Light data center). I tried creating a new character on this same server and I could play without disconnections.
- This seems to be the same problem as this post, which I found after I posted this thread.

Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

As the linked post suggests, typically the 90002 error usually means there is a connection issue or interference with the game's servers. However, as it appears the issue only occurs for one particular character, we would recommend trying out the following troubleshooting steps to see if it helps with alleviating the issue:

If this is only affecting one character, then it may be something to do with your locally-saved settings. Go to 'My Documents' > 'My Games' > 'Final Fantasy XIV' and delete that folder. Right click on the folder itself after deleting the contents, if it is set as read only, please uncheck that. If there are any corrupted files that are associated only with that character, this will get rid of them. Deleting these local files will not delete the associated characters. Please note however, this will reset all in-game configurations to their default values.

Aside from the above suggestion, please perform the following for best practice suggestions:

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

I tried every suggestion (in particular deleting locally-saved settings) but the problem still persists. The best I could do before getting disconnected in ~15 attempts is to teleport to Limsa, where I could not see my character at all.

As I said, I do not have any problem with a freshly created character on the same server. Can't the problem reside on the server side? Is there an official way to request an investigation on the character or some sort of restoration procedure?

[EDIT] With a VPN, I could connect and play without problem with my main character. It seems other people have similar connection problems with the same ISP (Orange) and in the same region (SE of France): https://forum.square-enix.com/ffxiv/...%C3%A8en/page4

Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums. We are glad to hear that you may have found a workaround, if you would like to continue troubleshooting please refer to the steps below.

If this is only affecting one character, then it may be something to do with your locally-saved settings. Go to 'My Documents' > 'My Games' > 'Final Fantasy XIV' and delete that folder. If there are any corrupted files that are associated only with that character, this will get rid of them. Please note, this will reset all of your in-game configurations back to their default values.

Please be sure to install Steam as well as the game to the C: drive as this works best with Final Fantasy XIV. Lastly, please be sure that no background processes are interfering with FFXIV (i.e. Anti-virus software, OneDrive, Discord etc.)
