How to fix FFXIV 10105 error?

Wait it out

Several sources have reported that the issue occurs on Square Enix’s side, so there’s little you could do about it. At some point, this error occurred shortly after the FFXIV game servers were targeted by a DDOS attack.

Thus, it would appear that the most suitable way to bypass the error is to avoid playing the game until someone confirms that it’s been dealt with. Especially if you plan on jumping head-first into a difficult, time-consuming trial.

Use a VPN

Sometimes, the situation can be caused by your ISP’s poor traffic routing or ISP bandwidth throttling. If you suspect that’s the case, you can use a VPN to circumvent your Internet provider’s limitations.

  1. Purchase a premium VPN subscription plan (we recommend Private Internet Access)PIA FFXIV
  2. Download the VPN and install it on your PC
  3. Launch it and log into your account
  4. Connect to a fast server (nearby servers are generally faster)
  5. Launch FFXIV
  6. Check if you still get error 10105

Note that using a VPN while playing FFXIV can also fix packet loss, and reduce in-game ping. If you want to unblock regional restrictions, for instance, using a VPN will also work wonders.

Use Ethernet instead of Wi-Fi

Not only with FFXIV, but whenever possible, make sure to always choose Ethernet over Wi-Fi. Wireless connections are much slower, they’re not as stable, and they’re prone to interference.

Also, Wi-Fi packet loss happens way more often than while using Ethernet.

While we’re on the topic, make sure that your Ethernet cables are not outdated, worn out, or damaged in any way. Bad cables could also have a great impact on how fast and stable your connection can be.

If you just switched to Ethernet, make sure to restart your router, to avoid any address assignment problems.

Flush your DNS

  1. On your Windows PC, launch a CMD instance
  2. Type the following commands, one by one, in this order:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
exit

Restart your PC, launch FFXIV, and try connecting to the server once more. Quite often, leaving cache data to build up can lead to various connectivity issues.

Flushing and renewing your DNS address can solve many connection problems, including not being able to log into various games.

Alternatively, you can replace your ISP-assigned DNS addresses with public free ones. For instance, you can use Google’s Public DNS or Cloudflare’s.

You may notice some improvement upon replacing your DNS, but make sure you backup the ISP ones, just in case something goes wrong.

Configure Internet Explorer

  1. Launch Internet Explorer on your PC
  2. Press Alt+X on your keyboard (or click the gear-shaped button)
  3. Select Internet Options from the menuLaunch Internet Explorer Windows 10

      2. Check all boxesDelete Browsing History Internet Explorer
      3. Click Delete
    2. Security tab:

      3. Check all the TLS and SSL boxes except SSL 3.0Internet Explorer SSL TLS settings
      4. Click the Apply button, then the Ok one

The reason why you need to configure Internet Explorer is that the game launcher reportedly uses IE to connect to the Internet. Therefore, if there are any settings that restrict the game in any way, you’ll probably have a difficult time connecting.

Apply compatibility settings

  1. Right-click the FFXIV launcher executable
  2. Select Properties from the combo menu
  3. Head over to the Compatibility tab
  4. Select Windows 7 from the Compatibility mode menu
  5. Check the Run this program as an administrator option
