zhangwenjian opened a new issue #4177: URL: https://github.com/apache/apisix/issues/4177
### Issue description I use openresty as my tcp protocol gateway, you can imagine that is a rdp gateway. The tcp client will send final server ip address after connected with gateway, and the balancer_by_lua_block will call set_current_peer to set the assigned server ip address as final backend. Then I need to response to the client that server is connected successfully or failed. But after set_current_peer returns, I don't known whether final backend server can be connected. How do to get the result and notify my client? -- This is an automated message from the Apache Git Service.
