Почтовый запрос curl не работает с опцией --http2, но отлично работает, когда я использую --http2-prior-knowledge

Я создал приложение с весенней загрузкой с tomcat 9.0.16, spring-boot 2.1.3.RELEASE, JDK1.8. Когда я делаю почтовый запрос curl с --http2, он говорит: «curl: (56) Ошибка получения: сброс соединения одноранговым узлом».

но когда я использую --http-preor-knowledge, он работает нормально.

мой файл application.property

server.port=8080
server.http2.enabled=true

и файл конфигурации

@Bean
    public WebServerFactoryCustomizer tomcatCustomizer() {
        return (container) -> {
            if (container instanceof TomcatServletWebServerFactory) {
                ((TomcatServletWebServerFactory) container)
                        .addConnectorCustomizers((connector) -> {
                            connector.addUpgradeProtocol(new Http2Protocol());
                        });
            }
        };
    }
