Failed to connect to instance

I was unable to join the instance to the waystone I opened in Atlas, after I clicked on the portal and to the loading screen. The game directed me to the log in screen with error message "Disconnected. Failed to connect to instance"

It happened to me since 3 days ago. This issue occurred randomly while sometimes I could go into the map (or by replacing a new waystone to the same Atlas).

I have tried using all different Renderer options (DirectX11,, DirectX12 and Vulkan), switching different servers (Singapore, Hong Kong, Japan and Auto-Select), log out my sync account in FilterBlade, using POE2 client (normally I use Steam to play the game), however the problem still exist.

Need solutions urgently!
