Additional information as requested in the instructions are at the bottom of this post.
I created my account on this forum, set the server password and am trying to login in the game.
I added the hook from the C&C online launcher and this seems to work fine. When clicking start game in Steam, the launcher is launched.
In Zero Hour > Multiplayer > online > i fill in my emailadress, nickname and password.
After logging in I get the error in the screenshot below.
I confirmed that my password is correct, because when I enter a wrong password on purpose I get the incorrect password notification.
What I already tried to resolve this issue:
Complete re-install of C&C ZH, C&C Online and deleting all game files from my documents + clearing the register records for the game.
Manually changing the register key for the game by adding dashes to the key or even completely replacing the key with "0000-0000-0000-0000-0000"
Disabling my windows firewall
What can I try additionally to resolve this?
Game Version: Steam Ultimate collection
Windows version: Windows 10 Pro
