Error 90006

Hello
i keep getting disconnected while playing i have abnormal lag spikes witch makes doing anything remotly difficult impossible i always get the error 90006

- When the issue started happening:about 2 weeks ago
- Platform: PC (steam)
- Any error codes or messages you receive upon disconnect (if any)
- Type of connection: Wired
- Other programs running while the game is playing: Discord, chrome the usual but even with everything closed it doesnt change a thing

- Everything you have tried to resolve the issue: first of all i tried to follow the indications on this old forum post https://forum.square-enix.com/ffxiv/...9-90006-%21%21 i did pretty much all it was asking exept checking the modem port ranges cause i dont know how to, i also tried the command ipconfig /flushdns in cmd

Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

We apologize for the delay in our response, please try the following troubleshooting steps:

- 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.
