The Secure Socket Tunneling Protocol service either could not read the SHA1 certificate hash from the registry or the data is invalid. To be valid, the SHA1 certificate hash must be of type REG_BINARY and 20 bytes in length. SSTP might not be able to retrieve the value from the registry due to some other system failure. The detailed error message is provided below. SSTP connections will not be accepted on this server. Correct the problem and try again.
