1. Configure nginx

After nginx is configured, you need to configure nginx and set https access.

}

2. Configure tomcat

Configure the conf/server.xml configuration under the tomcat directory. If you don't copy directly, there may be problems with your coding. It's better to add parameters on my basis

 <Connector port="8080" protocol="HTTP/1.1"
            connectionTimeout="20000"
            URIEncoding="UTF-8"
            redirectPort="8443"
            proxyName="jenkins.yellowcong.net" 
            scheme="https" 
            proxyPort="443" />

After restarting tomcat, that annoying mistake finally disappeared.
