Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  Expired Certificate: The primary cause of this error is that the digital certificate used for secure communications has reached its expiration date. Certificates have a validity period, and once this period is over, the certificate is no longer considered valid.

  Solution:
  
  
  Renew the Certificate:
  
  Obtain a new certificate from a trusted Certificate Authority (CA) or generate a new self-signed certificate if appropriate for your environment.
  If using a CA, follow their procedures for certificate renewal.
  
  
  
  Update the Certificate in SAP:
  
  Go to transaction STRUST in the SAP GUI.
  Navigate to the appropriate certificate store (e.g., SSL server, SSL client, etc.).
  Import the new certificate into the relevant trust store.
  Ensure that the new certificate is correctly configured and that any necessary intermediate certificates are also imported.
  
  
  
  Check Certificate Validity:
  
  After importing the new certificate, check its validity to ensure it is active and correctly configured.
  You can do this by selecting the certificate in STRUST and checking its details.
  
  
  
  Restart Services:
  
  Depending on your SAP system configuration, you may need to restart the relevant services or the entire SAP system for the changes to take effect.
  
  
  
  Monitor for Future Expirations:
  
  Implement a monitoring system or process to track certificate expiration dates to avoid similar issues in the future. This can include setting reminders for renewals.
  
  
  
  Related Information:
  
  Transaction STRUST: This transaction is used to manage SSL certificates and trust relationships in SAP systems.
