Unable to connect to POE

I having the connection issue to POE, yesterday I still playing POE without any issue (technically I still playing POE on 7/2/23, and after I have a sleep, (around 6hour later) I unable to connect to POE.)

Gateway: Singapore
Login with Steam

It say
>Connecting to login server...
>An unexpected disconnection occurred.

I have check the technical support and tried all of those, but none of them works, the link: https://www.pathofexile.com/forum/view-thread/305066/page/1

I also have restart my internet and PC, but it still unable to connect to POE. Other than POE, all application that need internet is able to run.

I also have try changing the gateway, but it still failed.

I also have contact my friends which is playing on Singapore gateway too, and they say having no issue on the login.
