Beginning in SAS Viya LTS 2025.09, the SSLREQCERT SAS environment variable is ignored when you set the variable to ALLOW:
OPTIONS SET=SSLREQCERT ALLOW;
You can confirm that the environment variable is set by executing the following SAS code:
%put &sysget(SSLREQCERT);
If you enable TRACE‑level logging for the App.tk.eam.ssl logger (as shown below), the log shows that the SSLREQCERT value is not recognized:
%log4sas();
%log4sas_logger('App.tk.eam.ssl', 'level=trace');
The following message occurs in the log:
ClientContextInit: SSLREQCERT not set. Assuming DEMAND
There is no workaround for this issue.
A patch for SAS Viya LTS 2025.09 is available. See Apply a Patch Update for additional information.
