把你的 Nebula 版本和 Importer 的版本补充下，你这个报错信息的话应该是端口没有配置好，把你的配置文件也贴下

31099是我服务器对外开放的端口
192.168.255.255是我服务器的ip（非真实ip)
请问在这样的环境下，应该怎么修改如下配置才能使得可以从外部浏览器访问studio呢，本人对网络底层原理不太了解。恳请释疑，谢谢了！

ngnix.conf配置
server {
    listen       31099;
    server_name  192.168.255.255;
    resolver 192.168.255.255 ipv6=off;

    location / {
        proxy_pass         http://web:31099;
        proxy_redirect     off;
        proxy_set_header   Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Host $server_name;
        client_max_body_size 1024M;
    }

    location /upload-dir/ {
        root /;
        autoindex on;
    }

    location ~ ^/api-nebula/([A-Za-z0-9\/]+) {
        proxy_pass http://client:31099/api/$1;
    }

    location ~ ^/api-import/([A-Za-z0-9\/]+) {
        proxy_pass http://importer:31099/$1;
    }

docker-compose.yml配置

不用修改 nginx.conf。只要修改这部分就可以打开 studio 啦，你试试

谢谢，按照你的方法修改端口映射终于成功了!另外我不得不说反复失败还有一个根本原因，我之前访问的ip地址根本就是是错的
