Hi 姚伟斌,

We have tested it on test environment and it is working now; and thanks to you! :)

However, in our test environment we also wanted to test nginx_tcp_proxy_module for WebSocket. We have noticed upstream server health check and status monitor bundle to the nginx_tcp_proxy_module.

Can you tell if we compile nginx_tcp_proxy_module, we can drop the nginx_http_upstream_check_module; and we still patch the nginx-sticky-module with nginx_http_upstream_check_module/nginx-sticky-module.patch and use nginx_tcp_proxy_module for upstream health check also..?

BTW: We have tried to compile both nginx_tcp_proxy_module and nginx_http_upstream_check_module together, following error fires during the make process.
