Yes really @WeMakeBest . It was my laptop’s new anti-virus firewall which was blocking the localhost site/port to be accessed by anyone (Also by my phone) I checked using my phone’s browser and it was not accessing localhost. As of now, I was just checking using my Laptop’s browser and IP Address. I just turned off my Anti-Virus Firewall and now it starts working.
Sorry, it wasn’t a problem with Kodular or script. I just installed new anti virus and also tried new method to fetch and store data in MySql and this error occurred hence i thought I am doing something wrong with this method.
Thanks again all of you for helping me out.
