how to reconnect TCP connection automatically

how to reconnect TCP connection automatically?

i try to use timeout 7200 seconds (2 hours) its ok, but if i use more than 7200 seconds times make it wrong. 

actually in the esp8266 datasheet maximum we can use 28800 seconds timeout so why goes error.

the soultion maybe we must reconnect TCP connection automatically after 7200 seconds max.

anyone can help me.

regards
