We are the facing almost the exact same issue with Windows 10 after some users change their AD password (not impacting everyone). As I understand, "ERROR_WINHTTP_CLIENT_CERT_NO_ACCESS_PRIVATE_KEY" is an error message from Windows.I've been trying to find anything relevant in windows event viewer, with no luck.Any pointers to where to look?Įdit: Just to make it clear, when I look at the client-cert in mmc, it states that the private key exists. The key is stored on TPM.What really puzzles me, when I connect the laptop to the corp wired network, it authenticates fine with the same certificate(!)The windows guys at work belives this is a globalprotect issue, but I (the network guy) find this hard to believe. Winhttpobj, cert do not has private key? clean lastIssuerName now, data = 0000000000000000 WinhttpObj, got ERROR_WINHTTP_CLIENT_CERT_NO_ACCESS_PRIVATE_KEY, clean cert cache now Įrror = ERROR_WINHTTP_CLIENT_CERT_NO_ACCESS_PRIVATE_KEY We've been using client certificates to authenticate users on VPN for some time.Been working great on windows 10, but now we've deployed some win 11 test clients and it fails.Īfter looking at the logs (we're using Palo Alto Globalprotect): winhttpObj, only one cert found, use this cert to retry, cert name is.
