Cannot log in to PoE2 — "Unexpected disconnect" after authentication

Hi GGG,

I’m currently unable to log into Path of Exile 2 via Steam. After launching the game, it shows:

- Connecting to login server
- Authenticating user
- Unexpected disconnect occurred

I’ve already tried the following:

- Verified Steam game files
- Cleared AppData (Local and Roaming) Steam folders
- Allowed PoE2 through Windows Firewall (private and public)
- Ran Steam as administrator
- Ensured Steam and PoE2 are both on the same drive
- Used Cloudflare WARP VPN (still same result)
- Linked my Steam account on the PoE website successfully

Could you please help or escalate this issue?

Thank you in advance.
