I have a listener waiting for connections from SC users on a non-standard port. Been doing this for many years and its superb.
There is one annoyance at the listener end - pop up messages: Connection failed - invalid protocol.
I get the odd one all the time but sometimes it might be 30 in a row - or more. A major pain to close them. Sometimes I resort to terminating the listener and then have to remember to restart it manually.
These are obviously coming from port scanners looking for other things.
Would it be possible to silently ignore such failed connections? The pop-up really serves no purpose. Or terminate then after a short pause?
