• Message: SSL0231W: Handshake Failed, Could not verify MAC.

  • Reason: The communication between the client and the server failed.

  • Solution: Retry the connection from the client.

• Message: SSL0232W: Handshake Failed, Unsupported SSL protocol or unsupported certificate type.

  • Reason: The communication between the client and the server failed because the client is trying to use a protocol or certificate which the IHS does not support.

  • Solution: Retry the connection from the client using an SSL Version 2 or 3, or TLS 1 protocol. Try another certificate.

• Message: SSL0233W: Handshake Failed, Invalid certificate signature.

• Message: SSL0234W: Handshake Failed, The certificate sent by the peer expired or is invalid.

  • Reason: The partner did not specify a valid certificate. The server is acting as a reverse proxy to an SSL URL and the _server_ cert could not be validated.

  • Solution: Partner problem. If this occurs during an SSL Proxy connection, the remote SSL server sent a bad certificate to IHS. Check the certificate and certificate authority chain at the other end of the SSL connection. For more information, see Securing with SSL communications.
