Hey everyone,
I’m hoping someone has an idea because I’m completely out of things to try.
The issue:
Warzone launches, but I can only play Battle Royale. Everything else is locked behind Limited Matchmaking, and I get a Failed Attestation message.
My PC:
Windows 11
Ryzen 7 2700X
GTX 1070
ASUS Prime X470-Pro motherboard
TPM 2.0 enabled and showing “Ready for use”
Secure Boot enabled
UEFI enabled
The game worked perfectly before. This all started after a Windows update a couple of months ago.
Everything I’ve tried:
Updated Windows completely.
Updated my motherboard BIOS.
Verified TPM 2.0 is enabled and ready.
Verified Secure Boot is enabled.
Confirmed UEFI mode is enabled.
Ran Battle.net Scan & Repair.
Completely uninstalled the game from Battle.net and downloaded a fresh copy on Steam.
Verified the Steam game files.
Ran DISM and SFC scans.
Disabled Wallpaper Engine.
Checked that my PC meets all the security requirements.
Restarted my PC countless times.
At one point the game wouldn’t launch at all, but after all the troubleshooting it finally opens. The only problem left is the Failed Attestation / Limited Matchmaking issue, so I can only access Battle Royale.
Has anyone actually fixed this? Is there something obvious I’m overlooking before I keep waiting on Activision Support?
Any help would be appreciated because I’m honestly stumped. Thanks!
