| |
| ERROR_SSL_BAD_RECORD_MAC | 75778 (0x12802) | The peers failed to negotiate a shared key material. Try connecting with different cipher suites one-by-one and check if any of them helps. If neither does, try to use a different protocol version. | |
| ERROR_SSL_DECRYPTION_FAILED | 75779 (0x12803) | ||
| ERROR_SSL_DECODE_ERROR | 75792 (0x12810) | ||
| ERROR_SSL_DECRYPT_ERROR | 75793 (0x12811) | ||
| ERROR_SSL_RECORD_OVERFLOW | 75780 (0x12804) | Packet size too large. Try to decrease the maximal size of the packet by adjusting the MaxFragmentLength extension. | |
| ERROR_SSL_DECOMPRESSION_FAILURE | 75781 (0x12805) | Compression or decompression failure. Switch off compression (CompressionAlgorithms property). | |
| ERROR_SSL_HANDSHAKE_FAILURE | 75782 (0x12806) | Incompatible versions or cipher suite lists. Try to play with version and cipher suite sets. Check that the server certificate is provided and has an associated private key. | |
| ERROR_SSL_ILLEGAL_PARAMETER | 75789 (0x1280D) | ||
| ERROR_SSL_NO_CERTIFICATE | 75783 (0x12807) | The certificate provided by the peer is not valid. | |
| ERROR_SSL_BAD_CERTIFICATE | 75784 (0x12808) | ||
| ERROR_SSL_UNSUPPORTED_CERTIFICATE | 75785 (0x12809) | ||
| ERROR_SSL_CERTIFICATE_REVOKED | 75786 (0x1280A) | ||
| ERROR_SSL_CERTIFICATE_EXPIRED | 75787 (0x1280B) | ||
| ERROR_SSL_CERTIFICATE_UNKNOWN | 75788 (0x1280C) | ||
| ERROR_SSL_UNKNOWN_CA | 75790 (0x1280E) | ||
| ERROR_SSL_ACCESS_DENIED | 75791 (0x1280F) | The requested application-layer resource cannot be accessed by the requestor. Check with the administrator of the remote resource. | |
| ERROR_SSL_EXPORT_RESTRICTION | 75794 (0x12812) | The peer is only configured to use exportable cipher suites. Switch on support for “EXPORT” cipher suites. | |
| ERROR_SSL_PROTOCOL_VERSION | 75795 (0x12813) | The peers have not been able to negotiate a version to use (no shared protocol versions). | |
| ERROR_SSL_INSUFFICIENT_SECURITY | 75796 (0x12814) | The cipher suites mutually supported by the peers are too weak and do not provide an adequate level of security. | |
| ERROR_SSL_INTERNAL_ERROR | 75797 (0x12815) | Contact the vendor. | |
| ERROR_SSL_USER_CANCELED | 75798 (0x12816) | Application layer has shut down the connection. | |
| ERROR_SSL_NO_RENEGOTIATION | 75799 (0x12817) | One of the peers requested a renegotiation, which was refused by the other. Note that you will get this error (as a warning) if you return Allow = false from the OnRenegotiationStart event handler. | |
| ERROR_SSL_CLOSE_NOTIFY | 75800 (0x12818) | Does not indicate an error condition. The SSL connection was closed gracefully and can be restored or cloned in future. | |
| ERROR_SSL_UNKNOWN_PROTOCOL_ERROR | 75801 (0x12819) | ||
