Re: Intermittent TLS inbound failure behind HAProxy, Kamailio opens new TCP to HAProxy ephemeral port and gets RST

Questions
    1.	Under which conditions does Kamailio decide to open a new TCP connection to the Contact instead of reusing an existing TLS connection?
    2.	If connection ID lookup fails, is fallback to active connect the expected behavior?

```
route[LOCATION] {
	if (!lookup("location")) {
		$var(rc) = $rc;
		t_newtran();
		switch ($var(rc)) {
			case -1:
			case -3:
				send_reply("404", "Not Found");
				exit;
			case -2:
				send_reply("405", "Method Not Allowed");
				exit;
		}
	}

	set_forward_no_connect(); # here you are
	route(RELAY);
	exit;
}
```

But this might not help you. The key point is why the TCP connection between HAProxy and Kamailio gets disconnected—who sent the TCP disconnect.
