The documentation is not exact in this case. Connect retry time is a kind
of timeout - if connection is not established until that time, it is retried.
But if the connection explicitly fails (like when 'no route to host'
is received) it is not used.

The behavior is:

start:
wait for start delay time
try to connect
if error received then goto start
if connect retry time reached and still no connection then goto start


So you have to either raise start delay time or just ignore it.
