那是因为你 gunicorn 绑定的是 127.0.0.1:8077 ，并没有绑 0.0.0.0:8077 ，所以当然通过外网 ip:8077 不通了

gunicorn 绑 127.0.0.1:8077 不变
nginx 配置类似：
listen 80;

location / {
try_files $uri @proxy_to_django_app;
}

location @proxy_to_django_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# enable this if and only if you use HTTPS
proxy_set_header X-Forwarded-Proto https;
proxy_set_header Host $http_host;
# we don't want nginx trying to do something clever with
# redirects, we set the Host: header above already.
proxy_redirect off;
proxy_pass http://127.0.0.1:8077;
}
