@Turla ,

How are you trying to connect? Via the browser or EG?

through the java code

public static void main(String[] args) throws IOException, CASException, KeyManagementException, NoSuchAlgorithmException {
            
            //-----------------------
            CASClientInterface client = new CASClient("**.**.**.**", 5570, "****", "****"); // 1

            String path = "CASUSER.HEART";
            String table = "HEART";
            String vars = "Status,sex,AgeAtDeath,Weight_Status,Smoking_Status";

            //обращаемся к таблице
            if (path != null){
                LoadTableOptions lto = new LoadTableOptions();
                lto.setPath(path);
                client.invoke(lto);
            }

            //создаем настройки выборки
            FetchOptions opt = new FetchOptions();
            Castable tble = new Castable();
            tble.setName(table);
            String[] vrs = getStringArrayProperty(vars);

            if(vrs != null){
                tble.setParameter(Castable.KEY_VARS, vrs);
            }

            opt.setTable(tble);
            opt.setSasTypes(false);

            //выбираем данные
            CASActionResults<CASValue> results = client.invoke(opt);
            //выводим результат
            if (results.getResultsCount() > 0){
                dumpByRow((CASTable) results.getResult(0).getValue());
            }
        }

@Turla ,

The root CA certificate needs to be provided to CAS clients. Clients include SAS 9.4M5 clients that can directly access CAS, SWAT (Java, R, Lua), Python, and REST clients. Please see more details in SAS® Viya® 3.5 Administration -> Data in Motion -> How To.
