Smart SAP Assistant

• What is the cause and solution for SAP error message SRT_WSP922 - No HTTPS protocol maintained on this server. X.509 auth. may not work! ?

  The SAP error message SRT_WSP922 indicates that the server is not configured to support HTTPS, which is necessary for X.509 authentication. This error typically arises in scenarios where secure communication is required, such as when using web services that rely on SSL/TLS for secure data transmission.
  Cause:
  
  HTTP instead of HTTPS: The server is configured to use HTTP instead of HTTPS, which means that secure connections cannot be established.
  SSL/TLS Configuration Issues: The server may not have the necessary SSL/TLS certificates installed or configured properly.
  Web Dispatcher or Reverse Proxy Issues: If a web dispatcher or reverse proxy is used, it may not be configured to handle HTTPS requests correctly.
  Firewall or Network Issues: Firewalls or network configurations may be blocking HTTPS traffic.
  
  Solution:
  
  
  Enable HTTPS:
  
  Ensure that the server is configured to support HTTPS. This typically involves installing an SSL certificate and configuring the web server (e.g., SAP Web Dispatcher, SAP Gateway) to listen on port 443 (or another designated port for HTTPS).
  
  
  
  Install SSL Certificates:
  
  Obtain and install a valid SSL certificate on the server. This can be done through a Certificate Authority (CA) or by using self-signed certificates for testing purposes.
  Ensure that the certificate is correctly configured in the SAP system.
  
  
  
  Configure SAP Web Dispatcher:
  
  If using SAP Web Dispatcher, ensure that it is configured to handle HTTPS requests. This includes setting up the SSL parameters in the Web Dispatcher profile.
  Check the icm/HTTPS parameters in the SAP profile to ensure they are set correctly.
  
  
  
  Check Network Configuration:
  
  Verify that firewalls or network security groups allow traffic on the HTTPS port (usually 443).
  Ensure that there are no network policies blocking HTTPS traffic.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the HTTPS connection to ensure that it is working correctly. You can use tools like curl or a web browser to check if the server responds over HTTPS.
  
  
  
  Review SAP Notes:
  
  Check for any relevant SAP Notes or documentation that may provide additional guidance or troubleshooting steps specific to your SAP version and configuration.
  
  
  
  Related Information:
  
  X.509 Authentication: This is a standard that defines the format of public key certificates. It is commonly used for secure communications over networks.
  SSL/TLS: Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are protocols that provide secure communication over a computer network.
  SAP Web Dispatcher: A tool that acts as a reverse proxy and load balancer for SAP applications, which can also handle SSL termination.
  
  By following these steps, you should be able to resolve the SRT_WSP922 error and enable HTTPS support for your SAP server.
