  Cause:
  The primary cause of this error is that the SSL certificate used for secure communication has reached its expiration date. Certificates are issued with a validity period, and once they expire, the system can no longer establish secure connections that rely on that certificate.
  Solution:
  To resolve this issue, you need to renew or replace the expired certificate. Here are the steps to do so:
  
  
  Identify the Expired Certificate:
  
  Check the details of the expired certificate to confirm its expiration date and the specific certificate that is causing the issue.
  
  
  
  Obtain a New Certificate:
  
  You can obtain a new certificate from your certificate authority (CA) or generate a new self-signed certificate if appropriate for your environment.
  
  
  
  Install the New Certificate:
  
  Once you have the new certificate, you need to install it in the appropriate location in your SAP system. This typically involves:
  
  Using transaction STRUST to manage SSL certificates.
  Importing the new certificate into the SSL client or server trust store.
  
  
  
  
  
  Update Configuration:
  
  Ensure that any configuration settings that reference the old certificate are updated to point to the new certificate.
  
  
  
  Restart Services:
  
  After installing the new certificate, restart the relevant SAP services to ensure that the new certificate is being used.
  
  
  
  Test the Connection:
  
  After the new certificate is installed and services are restarted, test the connection to ensure that the error is resolved and that secure communication with OSS is functioning correctly.
