Anyone still play Halo 1 PC (The original)?

I used to play Halo: Combat Evolved and it was working fine until I recently upgraded to Windows 11. The actual game loads fine, but it will not show any servers. I basically get that Gamespy message. I swear it was working recently, too just before upgrading from Windows 10. Any idea how to get it working again?

I’m guessing your installation hasn’t been updated to Version 1.10? If so, you have to update your installation to Version 1.10 to remove CE’s reliance on GameSpy for online multiplayer
