Need Help, Timeout Wifi Connections at Esp8266 and mobile app

// The code works for 5 sec. , after that the wifi connections interrupts
// I work with an rgb led strip, who should activated the led strip in colour red, when i push the button on the app.

//Maybe the line " void ledleiste(uint32_t color) { " works not cause, i havnt marked the color as an remotexy
