Getting a lot of 90002, 90001 and 2002 in Primal/Behemoth - Brazilian ISP

[Rammthota]

It started last week, never had this before.
Started with 90002 errors, then 2002 and now 90001.

I'm from Brazil and I don't see a lot of people of Primal in the forum with this problem. So I wonder what it is.

- Platform (PS4, PS5, Xbox): PC
- Wired or WIFI connection?: Wired
- When the disconnect occurs/How often? It depends, was every 20 min , now is 5 min every 5 min, sometimes i cant even login with a 2002 error.
- Does the disconnection happen to one character or multiple characters? I only use one character.
- Where in game do you get disconnected? All places.
- What ISP Is being used? Ligga Telecomunicações S.A.
- Is a VPN being used when this occurs? I do not use VPN.

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

Please try the following troubleshooting suggestions as it may help resolve the issue:

- Uninstall/reinstall the game.
- 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.
- We suggest to power cycle the device and router by shutting down the router and leaving the power supply unplugged for 30 minutes to an hour.
- 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.
- 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.

Lastly, check the following port ranges on your router/modem to ensure that the following port ranges have been opened/forwarded/triggered. You can contact your ISP and request they open them for you.

▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
