It happened in my QuickFixN application that FIX communication was not working. In logs I could see:

<event> Connecting to {IP} on port {Port}
<event> Connection failed: Connection refused {IP}:{Port}

Note that these logs are coming from the library.
After I restart my application (with the same configuration), FIX restarted working.

I am wondering if there is a way to catch this “connection refused” event. My application is based on the tutorial. If I could catch it, I could maybe try to recreate the SocketInitiator.

Thanks in advance!
