mbed Websocket connection issues

I have created a websocket server using java with netbeans IDE. My client is mbed K64F, which sends/receive the data to/from the java websocket server. Every thing is working fine so far, but I have few issues here 1) Mbed take 45 seconds to connect to websocket server: I dont know what is the main reason but my mbed client takes approx one min to connect to server, i think it looks like the handshake protocol is a bit different between mbed and java, can any one suggest some possible solution to reduce this time.

2) After every 2-3 hours the connection between server and client vanish: I couldnt figure out the possible reason but i tried to write a code to deal with this problem, that if connection goes down mbed should restart it self following is my logic

#include "mbed.h"
extern "C" void mbed_reset();
int main()
{
Websocket ws(ws://ip/myserver);
ws.connect();
printf("connected \n");
int count=0;
while (1)
{
if (ws.is_connected)
{
count++;
if (Interrupt)
ws.send("interrupt generated");
}
if (ws.read())
count--;

if (count>3)
NVIC_SystemReset();

}
}

Surprisingly (ws.is_connected) returns true after the connection drop as well, but it stopped to receive message from the server side so I made the logic as if it has not received any reply from server for more than 3 times it will restart it self.
