Seeking Help with Persistent "Failed to Connect to Instance" Error in PoE 2

Hello PoE Community and GGG Team,
I'm writing to report a critical issue affecting my gameplay experience in Path of Exile 2. After purchasing the game and creating a character, they are consistently unable to enter the game world. Upon clicking "Enter Game" from the character selection screen, the game crashes back to the login interface with the error message: “Failed to connect to instance.”

Steps to Reproduce:
Launch Path of Exile 2 and log into the account.
Select an existing character.
Click "Enter Game."
Game crashes to login screen with the above error.
Troubleshooting Attempts (No Success):
Restarted the game and PC multiple times.
Tested both wired and wireless internet connections.
Disabled firewalls/antivirus temporarily.
Reinstalled the game completely.
Restored the pc to factory settings and reinstalled all the NVIDIA display driver

System Specs (If Relevant):
OS: Windows 11
GPU: GeForce RTX 3070 (Drivers up-to-date)
CPU: AMD Ryzen 7 4800H
Internet: Default_F5DD6B (Stable connection, tested via other online games).

This issue has rendered the game unplayable despite the purchase, and these two days I am quite frustrated. Is this a known server-side problem? Are there any workarounds while a fix is being developed? Any guidance from the team or community would be greatly appreciated.
Thank you for your time and support!
