Method 3: Use VPN to Avoid Level3 ISP Node
This problem can happen at any time. Configure and enable your VPN favorite before attempting to connect to the Final Fantasy XIV game server if you already have one. Connectivity may be hampered by the usage of a VPN. Your connection may fail or slow down. If you don’t have access to a premium ISP, you’re likely experiencing drop-in connections with Final Fantasy as a result of considerable latency or packet loss between you and the server.

If you’re not using a VPN, the issue might be with your location. It’s possible that your server connection isn’t working properly. This occurs when the distance between the client and the server is greater.
