Hi,
After switching to 5.5.0-212, my test stopped working with the following exception:

com.prosysopc.ua.ServiceException: GetEndpointsResponse, endpoint list received from the server is empty.

The test setup is fairly easy:

***
var server = new UaServer();
server.setPort(4840);
server.setServerName(“OPCUA/Test”);
server.getSecurityModes().add(SecurityMode.BASIC256SHA256_SIGN_ENCRYPT);
server.setUserTokenPolicies(UserTokenPolicies.SECURE_USERNAME_PASSWORD_BASIC256SHA256);
server.setCertificateValidator(CertificateValidator.ALLOW_ALL);
var appDescription = new ApplicationDescription();
appDescription.setApplicationName(new LocalizedText(“TestServer”));
appDescription.setApplicationUri(“urn:test:opcua”);
appDescription.setProductUri(“https://example.org/opcua”);
appDescription.setApplicationType(ApplicationType.Server);
server.setApplicationIdentity(ApplicationIdentity.createCertificate(appDescription, “Test”, 512));
server.start();

client = new UaClient(“opc.tcp://127.0.0.1:14840/OPCUA/Test”);
var appDescriptionC = new ApplicationDescription();
appDescriptionC.setApplicationName(new LocalizedText(“TestClient”));
appDescriptionC.setApplicationUri(“urn:localhost:UA:TestClient”);
appDescriptionC.setProductUri(“urn:prosysopc.com:UA:TestClient”);
appDescriptionC.setApplicationType(ApplicationType.Client);
client.setApplicationIdentity(ApplicationIdentity.createCertificate(appDescriptionC, “TestClient”, 512));
client.setSecurityMode(SecurityMode.BASIC256SHA256_SIGN_ENCRYPT);
client.setUserIdentity(new UserIdentity(“User1”, “Pass1”));
client.connect();
***

While the client is connecting, an exception is thrown:

Interestingly, changing security to anonymous, as follows, all works fine (but I need to test the user sessions, so no real solution for me):

…
server.getSecurityModes().add(SecurityMode.NONE);
server.setUserTokenPolicies(UserTokenPolicies.ANONYMOUS);
…
client.setSecurityMode(SecurityMode.NONE);
…

Thanks!
