Fix Bitdefender Communication Failure: ‘Communication with Bitdefender App Service Failed to be Initiated
Some users have reported an issue where the Bitdefender interface fails to launch, displaying the error: “Communication failure. Communication with Bitdefender App Service failed to be initiated.” Additionally, reinstalling Bitdefender stalls at “Preparing Bitdefender Security” without progressing further.
Root Cause:
This issue is primarily due to missing or uninstalled trusted root certificates, especially the DigiCert Trusted G4 certificate. Without it, communication between the Bitdefender App Service and its components fails, resulting in the above error.
