Blynk connecting and ready repeatedly

Need Help With My Project
1

Hi, I am using Arduino Uno, Sim800l GSM Module and GPS Module in my project. I would like to ask why do Blynk keep connecting and ready as shown in the picture below? Is there any problem with my code? Thanks.

Try reading this, then asking yourself the question “is my void loop a problem?”
