scePsPcInitialize failed - SCE_PSPC_ERROR_IPMI_ERROR_TIMEOUT 0x8002051a
The game's first session today worked with SDK v4.00.00.15. Then the SDK auto-updated to v6.00.00.13 and worked for a while. After that, everything broke — even after reverting to v4.
The pattern is always the same:
PsPcSdkCore.exe Start ProcessId=XXXXX
--- 30 seconds pass ---
PsPcSdkSttTts.exe Connection timeout
PsPcSdkUI.exe Connection timeout
PsPcSdkTelemetry.exe Connection timeout
GoWR.exe Connection timeout
GoWR.exe [Initialization Error] Np initialization failed. errorCode=0x8002051a
GoWR.exe [Initialization Error] SDK initialization failed. errorCode=0x8002051a
PsPcSdkCore.exe starts but never opens its IPC channels. Every other component times out after ~30 seconds waiting for it.
What I've already tried (nothing worked):
- Restarted PC
- Ran install_pspc_sdk_runtime.bat as admin
- Uninstalled both MSIs (PsPcSdkRuntimeManager.msi + PsPcSdkRuntimeInstaller.msi), deleted C:\ProgramData\Sony Interactive Entertainment Inc, reinstalled fresh
- Deleted user data in AppData\Local\Sony Interactive Entertainment Inc\PSPC_SDK
- Renamed PsPcSdkUpdateChecker.exe to prevent auto-update
- Renamed PsPcSdkUI.exe to disable overlay
- Ran PsPcSdkAppMgr.exe as admin before launching
- Verified game file integrity through Steam
- Added Windows Defender exclusions for the game folder, SDK folder, and all PsPc executables
- Checked Windows Firewall rules (GoW is allowed)
