kubesphere使用nginx代理登陆pod终端显示错误处理

部署版本：Kubernetes 1.17 Kubersphere 2.1.1
目前 Kubesphere 已经部署成功，但是直接从网页访问 terminal 终端的功能，提示：could not connect to the container。
对于 kubectl 终端

 1、处理方式，需要配置nginx配置：

server {
    listen 80;
    include ssl-conf/ssl-full.loadttl.com.conf;
    server_name kubesphere.loadttl.com;  
    access_log /var/log/nginx/access.log json;
    error_log /var/log/nginx/error.log;
    index index.html index.htm;
    if ($ssl_protocol = "") { return 301 https://$host$request_uri; }

2、检查nginx配置，并加载配置

/usr/local/nginx/sbin/nginx -t
/usr/local/nginx/sbin/nginx -s reload

3、再次查看功能
