遇到nginx报错：websocket wss failed: Error during WebSocket handshake: Unexpected response code: 403

server { listen 6340; location / { proxy_pass ; proxy_http_version 1.1; #Nginx在与Node后端通信时使用HTTP/1.1，是WebSockets所必需的 proxy_set_header Origin ''; proxy_set_header Upgrade $http_upgrade; #Nginx响应升级请求，，当浏览器想要使用WebSocket时，该请求由HTTP启动 proxy_set_header Connection "Upgrade"; } }

代理 TCP和UDP

stream { upstream pptcp { server 10.10.10.10:9994; server 10.10.10.11:9994; } server { listen 9994; proxy_pass pptcp; proxy_connect_timeout 10s; proxy_timeout 3h; } upstream ppudp { server 10.10.10.10:9995; server 10.10.10.11:9995; } server { listen 9995 udp; proxy_pass ppudp; proxy_connect_timeout 10s; proxy_timeout 3h; } }
