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

Thank you for providing this information. Please try the following:

- 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 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

- Delete local files with corrupted character data, please note this will not delete the associated
characters

- Make sure your fire wall or antivirus program is not interfering with the game: I turned off windows firewall completely and still experienced the issue.

- 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.: I didn't see these ranges listening when I ran "netstat -a -n" in the command prompt, does that mean they aren't open?

- 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.: Tried this but still encountered the issue.

- 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.: Already tried this, see original post.

- Flush DNS: Within the "Command Prompt" of the device, please type the command "ipconfig
/flushdns".:Already tried this, see original post.

- Reset TCP/IP: Also within the Command Prompt, type the command "netsh int ip reset" and then

- Change local DNS: Please try changing the local DNS server to 8.8.8.8 and 8.8.4.4: Tried this, still encountering the error.

- Delete local files with corrupted character data, please note this will not delete the associated
characters: How do I know if they have corrupted character data and where are they located.

To those still struggling with this issue, I tried doing a continuous ping to the google servers by running the command "ping google.com -t" and found that when the disconnect occurs whenever that continuous ping gets a "Request timed out." I then looked at my modem's event logs and found some T3 timeout events that I'm looking into how to fix as I think those might be the cause of my own issue.
