docker中nginx转发失败

Question

在nginx配置文件中配置如下

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    #include /etc/nginx/conf.d/*.conf;

    server {
        listen       8083;
        server_name  106.55.9.3; #此处设置的是服务器ip
 
        location / {
            root       /usr/share/nginx/html;
            index      index.html;
            try_files  $uri $uri/ /index.html;
        }
 
        location /im {
            alias      /home/poetry-vue3;
            index      index.html;
            try_files  $uri $uri/ /index.html;
        }
        location ~ /api/ {
        fastcgi_buffers 256 128k;
        chunked_transfer_encoding off; 
            rewrite           ^/api/(.*)$ /$1 break;
            proxy_pass        http://106.55.9.3:8081;
            proxy_redirect    off;
            proxy_set_header  Host $host:$server_port;
            proxy_set_header  X-real-ip $remote_addr;
            proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        location /socket {
            proxy_pass          http://127.0.0.1:9324;
            proxy_http_version  1.1;
            proxy_set_header    Upgrade $http_upgrade;
            proxy_set_header    Connection "upgrade";
            proxy_read_timeout  600s;
        }
    }


}

这里监听了8083的端口，在nginx启动的时候也映射了宿主机的8083：8083端口，
希望能通过8083转发到8081端口做后端的请求，前端请求路径：http://106.55.9.3:8083/api/webInfo
实际后端接口路径是 8081/webInfo
发现无法转发，不知道问题出在哪里，求解答~

rewrite去掉 proxy_pass后面结尾加/api/

proxy_pass http://xxx.xxxx:8081/api/;
