> Hi @leslie-tsang, could you give some ideas on how to debug this issue? Yes for sure. > ### Issue description > **error log** > > ``` > [error] 48#48: *2240177 connect() failed (111: Connection refused) while connecting to upstream > > [lua] balancer.lua:327: run(): failed to pick server: failed to find valid upstream server, all upstream servers tried while connecting to upstream > ``` > > It can work sometimes, I try to increase times of retry for the route, but it can't solve this problem at all. Could you exec `curl` with `-v` to verify the network between apisix and upstream is working as expected ? e.g. ```shell curl -v http://upstream:port/uri ``` -- This is an automated message from the Apache Git Service.
