不知道为什么，nginx proxy_pass不起作用

Question

我配置了nginx prox_pass，但是它不起作用， 访问/正常，但访问/ v2 /时得到404 我的配置文件是：

服务器{

listen 80;

listen 443 ssl;

server_name my.com;

location / {

    proxy_pass http://localhost:8443;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_set_header X-Forwarded-Port $server_port;

}

location /v2/ {

    proxy_pass http://localhost:9443;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    proxy_set_header X-Forwarded-Proto $scheme;

    proxy_set_header X-Forwarded-Port $server_port;

}

}
