我用tomcat的nginx https代理遇到了同样的问题。这是因为我不支持wss请求。为了支持wss请求，我使用如下配置：
# WebSocketSecure SSL Endpoint## The proxy is also an SSL endpoint for WSS and HTTPS connections.# So the clients can use wss:// connections # (e.g. from pages served via HTTPS) which work better with broken # proxy servers, etc.server { listen 443; # host name to respond to server_name ws.example.com; # your SSL configuration ssl on; ssl_certificate /etc/ssl/localcerts/ws.example.com.bundle.crt; ssl_certificate_key /etc/ssl/localcerts/ws.example.com.key; location / { # switch off logging access_log off; # redirect all HTTP traffic to localhost:8080 proxy_pass http://localhost:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # WebSocket support (nginx 1.4) proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; }}
