Constantly lagging and disconnected 90006 (PS4)

Hi.

I am experiencing a constant lagging and error 90006 during rush hours (usually 8 pm GMT +7). At first it happened when I entered instances (duty finder etc.), but later on just by standing doing nothing I got heavy lagging and immediately disconnected. While this happened, all other connections were working just fine.

This happens in Elemental data center, Tonberry server and I am playing on PS4 using wireless connection.

I have tried reset the connection but it didn't help.
Kindly help with this issue.

Thank you.

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

We apologize for the delay in responding. Please try the following troubleshooting steps:

- Please make sure that "Cookies" and "JavaScript" are ENABLED on the PSN browser. If they are already checked, please uncheck them then recheck them.
- The issue could also be from the "Date & Time" settings on your PS4.
1. Close the FINAL FANTASY XIV game/application.
2. Go to [SETTINGS] on your PS4
3. Select [Date and Time], and "Set via Internet". (Please do not manually set the date and time.)
4. Once the date and time have been updated, please restart your PS4 console.
5. Once the console has fully restarted, please start the FINAL FANTASY XIV game/application.

Please make sure all other internet-enabled devices (including smartphones, laptop/desktop PCs, tablets, etc.) have been disabled and/or turned OFF to minimize game interference.

If the above steps do not resolve the issue, please 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
