Hi @Jythier - this error message means something is blocking the program from reaching the Internet. If your internet connection is working for other programs, try the steps below to see if you can identify the problem:
- Firewall and Antivirus - Make sure SimCity.exe and Origin.exe are added to exception lists. If you have BitDefender installed, disable it.
- Disable proxies
- SimCity.exe and Origin.exe - Set them to run "as administrator"
- Nahimic from MSI - this is an audio management program that comes with MSI motherboards. Disable or uninstall it. Nahimic 2 & 3 are known to cause this issue
- Disable Origin in-game In Origin main menu, right-click SimCity icon, Game Properties, check the box that says "Disable Origin In-game"
- Run in Windows 7 or 8 compatibility mode - right-click SimCity shortcut; choose Properties > Compatibility tab > Check the box to run in Win 7 or 8 compatibility mode
If none of these work, try a Clean Boot https://help.ea.com/en/help/faq/how-to-clean-boot-your-pc/ and attempt to launch SimCity. If it launches, you'll have some detective work to do. Enable one startup program at a time, reboot, try SimCity, until you find the program that is blocking it. Once you find the offending program, disable or uninstall it. You should be able to launch SimCity successfully without doing the clean boot after disabling the offending program.
Definitely post back and let us know whether something worked. If it still won't run, reply back with any error messages you're getting and attach a dxdiag report.
Happy Building!
