CC3000 WiFI shield delay problem

hello everyone,

I'm using CC3000 WiFi Shield to connect and insert some data to database. Now when I put the delay time on 1000 msec, everything works fine, and data is stored in database. But when I try to increase the time in delay on 2000 msec or higher there is problem and there is no storage then.

So if somebody can give advice what to do?

void loop(void)
{

    int t = 58;

    // Send request
    String request = "GET "+ repository + "insert.php?br="+t+ " HTTP/1.0";  
    send_request(request);
    
    delay(1000); // this works fine
    //delay(2000); there is no storage
}
