证书可能只在个人存储中（CurrentUser \ MyMy或LocalMachine \ My），它当然是自签名的。使用mmc检查证书是否在受信任的根存储中。如果没有在那里复制（可能在LocalMachine \Trusted Root中，以便所有用户都信任此证书）。

The certificate is probably only in Personal store (CurrentUser\My or LocalMachine\My) and it certainly is selfsigned. Check if the certificate is in Trusted Root store using mmc. If not copy it there (probably in LocalMachine\Trusted Root so that all users will trust this certificate).
