This happens on newer machines with Windows 11. The game needs to run in Backward Compatibility mode to access the servers (since win11 requires some security features that the game does not have), and Compatibility mode requires admin privileges.
Try running the game as Admin, that will mostly fix it. This is only necessary for the first startup. Once you enter the game and switch to single player mode, you no longer need Backward Compatibility so you can launch game normally after that.
If that didn't work, ensure that SimCity is not blacklisted by Windows Defender and it has Firewall Access.
