   I used you configuration to see wheather it's as same as yours.  I tried to close each port configured in the upstream and everything works well in the program.
   You can see if there is a warn log in the log file which means this host has been checked and it won't be choosen again.
   ```
   2020/11/14 02:14:23 [warn] 218476#218476: *33720 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/upstreams/1) unhealthy TCP increment (1/2) for '(9.23.27.226:7001)', context: ngx.timer, client: ::1, server: [::]:9080
   2020/11/14 02:14:25 [warn] 218473#218473: *33843 [lua] healthcheck.lua:1107: log(): [healthcheck] (upstream#/apisix/upstreams/1) unhealthy TCP increment (2/2) for '(9.23.27.226:7001)', context: ngx.timer, client: ::1, server: [::]:9080
   ```
   And if I close both ports, I can see the log just like you. 
   ```
   2020/11/14 02:22:51 [error] 218476#218476: *62776 connect() failed (111: Connection refused) while connecting to upstream, client: ::1, server: , request: "GET /route1 HTTP/1.1", upstream: "http://9.23.27.226:7001/route1", host: "localhost:9080"
   ```
   Here I use you ip and port to replace mine. :)
