请教下一个 nginx 反向代理的问题配置如下，内网 ip http://ip 可以跳到 https://ip 但是公网 ip 加端口映射这种方式不知道咋办了？

server {
listen 443;
server_name localhost;

ssl on;
ssl_certificate /etc/nginx/conf.d/server.crt;
ssl_certificate_key /etc/nginx/conf.d/server.key;

ssl_session_timeout 5m;

client_max_body_size 50m;

location / {
proxy_pass http://tomcat;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
}

}

server{
listen 80;
server_name localhost;
return 301 https://$server_name$request_uri;
}
