  The SAP error message 1S423: Cannot analyze certificate typically indicates an issue with the SSL/TLS certificate being used in the SAP system. This error can arise in various contexts, such as when establishing secure connections between SAP systems or when integrating with external services.
  Causes:
  
  Invalid Certificate: The certificate may be expired, not yet valid, or not properly signed by a trusted Certificate Authority (CA).
  Missing Intermediate Certificates: If the certificate chain is incomplete (i.e., missing intermediate certificates), the system may not be able to validate the certificate.
  Incorrect Certificate Format: The certificate may not be in the expected format (e.g., PEM vs. DER).
  Configuration Issues: Incorrect configuration in the SSL settings of the SAP system or the application trying to use the certificate.
  Trust Store Issues: The certificate may not be present in the trust store of the SAP system, or the trust store may not be properly configured.
  
  Solutions:
  
  Check Certificate Validity: Verify that the certificate is valid and has not expired. You can check the validity period and the issuer of the certificate.
  Install Missing Intermediate Certificates: Ensure that all necessary intermediate certificates are installed in the trust store. You can obtain these from the CA that issued the certificate.
  Convert Certificate Format: If the certificate is in the wrong format, convert it to the required format (e.g., using OpenSSL).
  Update SSL Configuration: Review and update the SSL configuration in the SAP system. Ensure that the correct paths to the certificate and key files are specified.
  Add Certificate to Trust Store: If the certificate is not in the trust store, add it. You can use transaction STRUST in the SAP GUI to manage certificates.
