   @spacewander 
   for APISIX 1.* nginx.conf should be this (to transparent proxy requests, include ws , wss..) (it is the ingress' default nginx.conf)
   
   ```
   http {
       ...
       
       + # See https://www.nginx.com/blog/websocket-nginx
       + map $http_upgrade $connection_upgrade {
       +     default          upgrade;
   
       +     # See http://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive
       +     ''               '';
       + }
   
       ...
   }
   
   server {
               + # Allow websocket connections
               + proxy_set_header Upgrade           $http_upgrade;
               + proxy_set_header Connection        $connection_upgrade;
   
               set $upstream_host               $host;
               + # set $upstream_upgrade            '';
               + # set $upstream_connection         '';
               set $upstream_uri                '';
   
               # proxy_http_version 1.1;
               proxy_set_header   Host              $upstream_host;
               + # proxy_set_header   Upgrade           $upstream_upgrade;
               + # proxy_set_header   Connection        $upstream_connection;
   }
   ```
