auto reconnect not work if the network break four hours when network recorvery

[leetb-leetb]

version 1.3.14, my code is blew:
conn_opts.automaticReconnect = 1;
conn_opts.minRetryInterval = 48;
conn_opts.maxRetryInterval = 96;
conn_opts.keepAliveInterval = 60;

when my netwok broken , i can receive MQTTAsync_connectionLost, but after four hours or more , my network recovery, the client can't auto reconnect, seem the client had sleepped, i must do something to wake up client，then it can auto connect, is there some settings which let client not sleep, always to retry to reconnect?
