I’ve got an app that connects to a number of tcp ports using :ranch_tcp.connect/3

I connect in passive mode and then switch to active once I get {:ok, socket}.
When I get the socket I execute a Telemetry message:

 case :ranch_tcp.connect(...) do
      {:ok, socket} ->
          ...
          :telemetry.execute(
            [:some, :key],
            %{active: 1}
          )
          ...

I call :telemetry.execute in each of handle_info({:tcp_closed, _socket}, _state ) and handle_info({:tcp_error, _socket}, _state ) where I set the active key to 0.

One of the systems I connect to is a back-up system that is only used if we need a fail-over for some reason. Thus there is only very infrequently traffic from that ip/port. When such a fail-over occurred I did not get any messages form the back-up connection.
Telemetry had not executed an active: 0 message.

So my question is:
Is there a way that a tcp connection in Ranch/gen_tcp can become inactive without being caught by {tcp_error, _} or {tcp_closed, _}?
