django uwsgi nginx websocket 搭建后台管理,本地没问题,上传服务器 websocket 报 502 错误,其他接口能正常访问

nginx 配置: server { listen 80; server_name 服务器地址; charset utf-8; client_max_body_size 75M;

location / {
    root /root/dist;
    index index.html;
    try_files $uri $uri/ /index.html;
   
}
location /api/ {
    uwsgi_pass 127.0.0.1:8001;
    include /etc/nginx/uwsgi_params;  
}
location /ws/ {
    proxy_pass http://127.0.0.1:8001;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   
}

} nginx 配置:

[uwsgi]
chdir = /root/....
home = /root/....
module = ....

master = True
processes = 2
harajiri = 60
max-requests = 5000

socket = 127.0.0.1:8001
uid = root
gid = root
pidfile = /root/master.pid
daemonize = /root/conf/logs/uwsgi_hzmj.log
vacuum = True
log-maxsize = 102400 
buffer-size = 65536

websocket 报错:
