Need help with configuring sslocal via docker.

I want to use sslocal running in docker. I have started docker with config looking something like:

{
  "servers": [
    {
      "address":"server_ip",
      "port":server_port,
      "password":"server_pass",
      "method":"server_method",
      "timeout":60
    }
  ],
  "locals": [
    {
      "local_port": 1080,
      "local_address": "127.0.0.1"
    },
    {
      "protocol": "http",
      "local_address": "127.0.0.1",
      "local_port": 1081
    }
  ]
}

And mapped ports 1080 and 1081 to the host ones. When using http proxy inside the container it works (with 1081 port), but using proxy outside the container (with the host port) - request fails. Host OS - Windows.

Start by comparing the working in-container HTTP proxy with requests through the host-mapped ports on Windows. Check the Docker port mappings and the configured local addresses and ports; the work is done when host requests successfully use the exposed proxy.
