Add logging to the query function like this and post what you get in Logs tab:

Code:

function query(req, out)
  if not sock then
    return
  end

  sock:send(req .. '\r\n')
  local res, err = sock:receive()

  if not res then
    return close(err)
  end

  if res:sub(1, 1) ~= '~' then
    return close('invalid reply ' .. res)
  end

  if res:sub(2, #req) ~= req:sub(2) then
    return close('invalid reply ' .. res)
  end

  local val = res:sub(#req + 2)
  log('response', req, out, val)
  val = tonumber(val)

  if val then
    grp.checkupdate(out, val)
  end
end
