遇到同样的错误 不过我是kubesphere的集群，host访问member的容器就会403，但是访问其他资源又是ok的
nginx配置
map $http_upgrade $connection_upgrade {
default Upgrade;
'' close;
}
upstream kubesphere_console {
server 172.18.1.110:30880;
keepalive 60;
}
server {
listen *:443;
ssl on;
server_name kubesphere.abc.top;
ssl_certificate /etc/nginx/ssl/abc.top.crt;
ssl_certificate_key /etc/nginx/ssl/abc.top.key;
location / {
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}
}
