Cannot configure mTLS Server as MockServerClient receives 426

[space88man]

Describe the issue After starting a mTLS ClientAndServer, the first when(...) rule causes ClientException termination with

10:18:42.262 [MockServer-EventLog0] INFO  org.mockserver.log.MockServerEventLog - no tls for connection:

  /127.0.0.1:12350

 returning response:

  {
    "statusCode" : 426,
    "headers" : {
      "Upgrade" : [ "TLS/1.2, HTTP/1.1" ],
      "Connection" : [ "Upgrade" ]
    }
  }

What you are trying to do

• configure a ClientAndServer with mTLS and client cert authentication
• note: outbound TLS not required

MockServer version The version you are using mockserver-netty, mockserver-client-java: 5.15.0

To Reproduce

    @BeforeAll
    static void setUp() {
        ConfigurationProperties.certificateAuthorityCertificate("keys/server-subca.crt");
        ConfigurationProperties.certificateAuthorityPrivateKey("keys/server-subca.key");
        ConfigurationProperties.x509CertificatePath("keys/server-server.crt");
        ConfigurationProperties.privateKeyPath("keys/server-server.key");

        ConfigurationProperties.tlsMutualAuthenticationRequired(true);
        ConfigurationProperties.tlsMutualAuthenticationCertificateChain("keys/server-truststore.pem");

       // outbound TLS not needed 
       // ConfigurationProperties.forwardProxyTLSCustomTrustX509Certificates
       // ConfigurationProperties.forwardProxyCertificateChain
       //  ConfigurationProperties.forwardProxyPrivateKey

        // now server will start and can be connected to by openssl s_client
        mockServer = ClientAndServer.startClientAndServer(12350);

       // this rule causes an error
        mockServer.when(request().withMethod("GET").withPath("/api/any/test"))
        .respond(response().withStatusCode(200).withDelay(TimeUnit.MILLISECONDS, 100)
                .withHeader("Content-Type", "application/json").withBody("{\"status\":\"test OK\"}"));

1. How you are running MockServer (i.e maven plugin, docker, etc): Java code in JUnit @BeforeAll
2. Code you used to create expectations: see above
3. What error you saw: Creating the expection causes 426

Expected behaviour Configure ClientAndServer with when(...) expectations

MockServer Log Log output, as INFO level (or lower)

returning response:

  {
    "statusCode" : 426,
    "headers" : {
      "Upgrade" : [ "TLS/1.2, HTTP/1.1" ],
      "Connection" : [ "Upgrade" ]
    }
  }

org.mockserver.client.ClientException: error:
org.mockserver.client.ClientException: error:

  null

 while submitted expectation:

    },

    },
    "times" : {
      "unlimited" : true
    }
  }

Closing: found the ::controlPlane* methods and the ::withSecure method in javadocs so that the MockServerClient will also use mTLS.
