• What is the cause and solution for SAP error message 00774 - Received X.509-client certificate not passed by HTTPS ?

  The SAP error message "00774 Received X.509-client certificate not passed by HTTPS" typically indicates an issue with the client certificate during an HTTPS connection. This error occurs when the SAP system is expecting a client certificate for authentication, but it is either not being sent or is not being recognized.
  Cause:
  
  Client Certificate Not Provided: The client (e.g., a web browser or another application) is not configured to send the required X.509 client certificate.
  Certificate Configuration Issues: The client certificate may not be properly installed or configured on the client side.
  Server Configuration: The SAP server may not be correctly configured to accept client certificates.
  SSL/TLS Settings: There may be issues with the SSL/TLS settings on either the client or server side.
  Certificate Trust Issues: The server may not trust the certificate authority (CA) that issued the client certificate.
  
  Solution:
  
  
  Check Client Certificate Installation:
  
  Ensure that the client certificate is correctly installed in the client application (e.g., web browser, Java application).
  Verify that the certificate is valid and not expired.
  
  
  
  Configure Client to Send Certificate:
  
  If using a web browser, ensure that the browser is set to prompt for a client certificate or automatically send the correct certificate.
  In some cases, you may need to configure the application to explicitly use the client certificate.
  
  
  
  Review SAP Server Configuration:
  
  Check the SAP server's SSL configuration to ensure that it is set up to require and accept client certificates.
  Ensure that the server's SSL profile is correctly configured to trust the CA that issued the client certificate.
  
  
  
  Check SSL/TLS Settings:
  
  Verify that the SSL/TLS settings on both the client and server are compatible.
  Ensure that the correct protocols and cipher suites are enabled.
  
  
  
  Certificate Trust:
  
  Make sure that the CA certificate is installed in the trust store of the SAP server.
  If necessary, import the CA certificate into the SAP system's trust store.
  
  
  
  Network Configuration:
  
  Ensure that there are no network devices (like firewalls or proxies) that might be interfering with the HTTPS connection or client certificate transmission.
