Создание

transport = GrpcTransport.forEndpoint(this.hostnames[0], configuration.get(DATABASE) + "/")
                                      .withCallExecutor(executor)
                                      .withAuthProvider(new TokenAuthProvider(ydbToken))
                                      .withSecureConnection(bytes)
                                      .build();

После вызова transport.closeиногда возникают исключения
