System error -2146697211

Hi. Today I started getting log-in issues for no apparent reason. It started with system error -2146697211. So far, I have tried
1. Restarting my router and computer.
2. Launched the game with my anti-virus turned off.
3. Ensured FF14 is whitelisted on my firewall.
4. Cleared my Microsoft Edge history made sure that "Privacy, Search and Services" is turned on.
5. Verified my game cache (I am playing on Steam).
6. Uninstalled the game, but I am also unable to re-download it due to the launcher crashing with the error code.

Sometimes, through sheer luck, I manage to get the launcher running to try and re-install the game. It works for about 3-4 minutes, then I get the error message "FFXIV Launcher Error, the server is not responding. For assistance with this issue, please visit the SQUARE ENIX Support Center. https://sqex.to/x4w [30413][10009][10019]". I visited the support center but could not find help there.

I play on Steam, have all expansions, playing on Europe servers (living in Europe), Spriggan.

Never had this issue before, and would love to get it to work again since I finally got my friends to play. Any help is appreciated!

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

The issue you are describing is most associated with interference with game data. Many actions can trigger this error, such as a slow internet connection, certain security/privacy changes on the default Internet browser, an application running in the background causing interference, use of a VPN or an odd connection (EG: schools or cafes), a possible virus detected on the device, many rapid payments at once, and numerous other actions.

We advise clearing the cache/cookies/browsing data from your default web browser, disabling any web browser extensions (EG: ad-blocker) and trying again. We also suggest resetting the connection (router/modem) you are using to connect to the Internet before trying again.

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

Lastly, 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 Router and leaving the power supply unplugged for 5-10 minutes.

Thank you for the response. I tried all of the things you suggested, and still no dice. I then tried to connect with a mobile hotspot, which worked, and then I need to turn it off because FF14 is obviously too draining for my phone connection. Is this a sign of ISP issues?

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

We are sorry to hear the provided troubleshooting was unable to help. If you are able to proceed with a different network, this would indicate that there is some sort of connection issue. At this time we would suggest contacting your ISP to double check your network.
