TcpServerBinder uses beforeOnError to log any failures to create a connection (to capture connection info) and then it goes to SimpleSingleSubscriber that logs it again.
Modifications:
Use new Single.subscribe(...) overload introduced in #3112 that takes errorConsumer to log "Failed to create a connection";
Log full Channel info instead of just remote address to keep a consistent pattern of starting all network-level logs with channel id;
