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), using private/incognito mode, or even on a different smart device with WiFi turned off and trying again. We also suggest resetting the connection (router/modem) you are using to connect to the Internet before trying again.

Thank you once again for visiting the Final Fantasy XIV Technical Support Forums!
