Android CertPathValidatorException как решить?

Я создаю SSLSocket для шифрованного подключения к серверам. На серверах настроено шифрование TLSv1.2

SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
                    sslContext.init(null, null, null);
                    SSLSocketFactory sslSf = (SSLSocketFactory) SSLSocketFactory.getDefault();
                    SSLSocket sslSocket = (SSLSocket)sslSf.createSocket(
                            mcSock,
                            mcSock.getInetAddress().getHostAddress(),
                            mcSock.getPort(),
                            false);
                    sslSocket.setUseClientMode(true);
                    sslSocket.startHandshake();

Когда я пытаюсь подключиться, у меня появляется ошибка:

Каким образом я могу обойти эту ошибку без TrustAllCerts и самоподписных сертификатов?
