springboot 开启https后，项目启动第一次可以成功访问，关闭浏览器再访问报错

Question

按照网上找的资料，使用keytool生成一个p12的证书，添加到项目中。之后项目可以正常启动并访问，http：8080，和https：443。
但是过一段时间，或者重启浏览器，https：443端口就无法访问了

chrome显示ERR_SSL_PROTOCOL_ERROR

后台报错：

我的配置文件如下
application.properties:

server.port=443
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=123456
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=michael

HttpConfig:

@Configuration
public class TomcatHttpConfig {
 @Bean
 public TomcatServletWebServerFactory servletContainer() {
 TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
 tomcat.addAdditionalTomcatConnectors(initiateHttpConnector());
 return tomcat;
 }
 private Connector initiateHttpConnector() {
 Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
 connector.setScheme("http");
 connector.setPort(8080);
 connector.setSecure(false);
 connector.setRedirectPort(443);
 return connector;
 }
}

keytool指令：

keytool -genkey -alias michael -dname "CN=Michael,OU=test,O=test,L=test,ST=test,C=CN" -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 365

为什么https要在项目中配置，建议是在NGINX中配置

server {
     #SSL 访问端口号为 443
     listen 443 ssl; 
     #填写绑定证书的域名
     server_name cloud.tencent.com; 
     #证书文件名称
     ssl_certificate 1_cloud.tencent.com_bundle.crt; 
     #私钥文件名称
     ssl_certificate_key 2_cloud.tencent.com.key; 
     ssl_session_timeout 5m;
     #请按照以下协议配置
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2; 
     #请按照以下套件配置，配置加密套件，写法遵循 openssl 标准。
     ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE; 
     ssl_prefer_server_ciphers on;
     location / {
        #网站主页路径。此路径仅供参考，具体请您按照实际目录操作。
         root /var/www/cloud.tencent.com; 
         index  index.html index.htm;
     }
 }
